i have 2 dogbones on my car. the lower one is the polyurethane one from the fiero store, and the top one looks like its the stock one. the rubber is blown. i can not tell if it is the stock one from the stock v6 or not. the joy of someone who just grabbed parts and used them without knowing where they came from.
When I bought my first replacement dogbone for my V6, I was thoroughly surprised that it didn't fit because at the time, I didn't know that even the factory dogbones --- even those just for V6s --- sometimes came in different lengths. In turn, when somebody purchases one, whether it's from a junkyard, or even brand-new (e.g., from The Fiero Store), sometimes it will fit, and sometimes it just won't.
However, unlike the first V6 replacement dogbone I purchased from somebody else, the adjustable dogbone from Rodney Dickman ( http://rodneydickman.com ) is a very worthwhile product which proved an excellent fix for the "too-short" dogbone problem I'd encountered earlier with my own V6 Fiero.

The problem is there is no one stock length for a V6 Fiero. It actually varies, something most people probably weren't aware of.
Interesting. Are you sure about this project34? Did you check to see if there were different part numbers in the P book for the different lengths?
For americasfuture2k: keep in mind that when you install the second bolt through the dog bone, you're supposed to pull the engine rearward with 55 lbs of force and hold the engine there while you tighten the bolt according to the service manual. This will help align the dog bone if you find that it's too short.

Well, I was sure about that, until you asked if I checked "to see if there were different part numbers in the P book for the different lengths," because I hadn't done that.
However, I am sure that for my `86 GT, I initially bought from The Fiero Store their part number 52799, what they call their "85-88 V6 Ultimate Dog Bone." Ultimately, it did not fit because it was much too short for my `86 GT.
Although I focused on only the first one below, I suppose the above suggests there could be at least two different explanations for The Fiero Store's dogbone not fitting:
There is no one stock dogbone length for V6 Fieros.
OR
There is only one stock dogbone length for V6 Fieros, but The Fiero Store offers the wrong length for them.
Whatever the best explanation for that dogbone fit problem, I'd still recommend avoiding it in the first place by purchasing Rodney Dickman's nicely adjustable dogbone for the V6 Fiero, rather than the fixed-length V6 dogbone from The Fiero Store.

i dont have the stock fiero engine, and was unsure of if that old ass dog bone mount my brother fashioned up a mount for on this engine was indeed a fiero stock mount or not. lol this is still in question from the answers im seeing.
americasfuture2k, are you just needing to replace the bushing? If so here's some ideas for you, 1st the rubber mallet "mod":
jimbolaya: For what it's worth, when I first bought my car it did not have a bone. I got one at the junk yard, but the bushings were shot. I cleaned the old ones out and then bought a rubber mallet at the dollar store. I cut the mallet head in half and removed the handle. I shaved to where it was slightly bigger than the hole in the bone. Then I pressed it into the bone opening. I drilled a hole in the center for the bolt and metal sleeve and voila! A new dog bone for a $1. 3 years later, it is still there.

Looks like yours has the internal ridge so here's a mod jetman did to his: https://www.fiero.nl/forum/A...060811-2-069534.html I'd probably mod the bushing to fit the dogbone and not the other way around but it seemed to work ok for jetman.
By the way I have seen 2 different style dog bones on the 2.8 V6. Yours appears to be an internal ridge and the other, an external ridge. This is an external:
The above is an automatic transaxle but my '86 Getrag/Muncie has the same style. As far as any difference in lengths, I honestly have no idea.
Originally posted by LT188GT: The only numbers that I can find in my P book are 10046816 for the 4 cyl and 10046818 for the V6
Well, that is interesting.
I see that the two 8-digit part numbers you've cited from your P book are identical, EXCEPT for their last digit, "6" for the 4-cylinder versus "8" for the V6. You and Bloozberry thus have inspired me to locate the original dogbone for my `86 GT, which of course, was a V6.
Having found that dogbone for my V6, I see that on one side of the "bridge" connecting the dogbone's two end cylinders is stamped what I assume to be the dogbone's part number. That 8-digit number is 10046812, identical to the only one for the V6 which you found in your P book, EXCEPT for its last digit, which is "2" on mine --- not "8."
It therefore would seem that the P book is not showing all the part numbers for the V6 Fiero dogbone, for which there appear to be at least two: 10046818 and 10046812.
If either you or Bloozberry have an original dogbone for a V6 Fiero, I'm curious to learn what the 8-digit number on it is, as well as the center-to-center distance between the between the two holes in the dogbone. On my 10046812 V6 Fiero dogbone, it's 4 inches.
americasfuture2k, I've the same two questions of you as well. Your answering them may help us to identify just what dogbone it is that you have.

well i was looking to fashion my own solid one like the one rodney sells, but that rubber mallet one sounds like a hella better and cheaper temp solution till i make my solid one. or but rodneys. cause hes the man.

I'll have to dig up the dog bone I know I have lying in a box somewhere for an '85, but on the two '88's I have in the shop right now, neither has a part number, they're both of the smaller web design (like the first picture in this thread), and both are on 4" centers. I'll post the additional info on the other dog bone when I find it.

do you have a link to that mallet post or thread?
Well yeah, Rodney is the man! We're very lucky to have people like him and all the others that support the Fiero community.
I received e-mail confirmation from Justin at The Fiero Store on January 8 that the center-to-center distance between the the two holes of The Ultimate Dogbone which they currently offer for all V6 Fieros is one and only one size: 4-1/2 inches.
In that regard, although it's not immediately obvious from the title of this archived 2006 thread, "need quick help from people with V6 cars" ( https://www.fiero.nl/forum/A...090219-2-079315.html ), be aware it contains much useful information about the different dogbone lengths in V6 Fieros, despite the P book showing only one part number for them.
Accordingly, to minimize any potential problems arising from differing dogbone lengths if you've a need to replace the dogbone on your V6 Fiero, you may want to opt for the easily installed, adjustable dogbone offered by Rodney Dickman ( http://www.rodneydickman.co...justabledogbone.html ).
