Anyone know the dimensions for the rear mounting bolts for an '88 engine cradle?

Thanks.

What dimensions do you need? I've got one I can go measure!

'88 Coupe (extensive mods underway)
https://www.fiero.nl/forum/Forum2/HTML/086359.html

I just bought new ones from the Fiero Store. They are kinda odd shaped.

The '88 front cradle bolts are readily available, but the rear bolts are not.

Do you know what size bolts are used for the rear mounting?

get em from Fierostore.com

youll get em in 3days.

I can't find the '88 rear cradle bolts at the Fiero Store (Only, the front bolts.) How about sending me the kink.
Thanks.

I need a set of FRONT cradle bolts, The OEMs have a small shoulder near the head of the bolt and then is slightly relieved as it goes toward the threads. The ones from the Fiero Store do not appear to be this way.

Can anyone explain?

So you are looking for these, eh?


The real question is....what are they worth?

For record, they are 12x1.75 thread, and 2.5" long (including the non-threaded part).

These are flanged bolt heads. The size of the front cradle bolts for an '88 is: M14 2.00(Thread size) 115mm(total length) 40mm(threaded length) 21mm(head size). I don't remember where I got mine, but I do believe you can check your local Fastenal. A flanged head will give the bolt more contact with the surface - spreading the load across more of the material than a standard head. If you could get a strong (10.9) washer to use, a non-flanged bolt + washer combo would do fine (take into account the washer size when buying the bolt length).

Guys-

I did not explain correctly. Here is a shot of one of my one front cradle bolts. note the short shoulder.


The one above looks good.

Here is the other one and is the reason I need a new one. Rust ate the threads.


The FS ones don't look like they have this short shoulder. Do they?

Can anyone comment on the front mounting bolts shown and how they compare to the ones at FS?
