I have an extra cradle and want to know if I can see what type it is.
Are there different models for 4 and 6 cil. or different years?
Please advice me.

Someone correct me if I'm wrong but I think there is the 1984 cradle (V6 will not fit without mods), the 1985-87 cradle and the 1988 cradle. The 88 cradle will have the 88 suspension setup so it should be easy to spot. 85-88 cradles accept both L4 and V6 engines.

How can I see the difference between the different versions? especially the 84 and the 85-87 ones?

I don't know, I have never seen a 84 cradle before. Someone can help?

The only diff on the 84 cradle is that it is missing the mounting boss for engine torque strut. (tiny small block shock looking thing) Aside from that it is pretty much the same.

I used an 84 donor cradle when I converted my 85GT to a stick shift. It is a simple mater of drilling 2 or 3 holes and then either threading them, or using nuts and bolts. Everything else is the same. There were no major changes in the 84-87 cradles.

I also believe that the tie rod mounting points are in an ever so slightly different position on the 84 cradles.
I believe an 87 4cyl auto cradle also has a additional mount.

There are actually 5 different cradles by P/N. The 86-87 4 cyl auto is (10039428) and has probably a uni-mount trans bracket. The 22P lists cradle (10003671) for 4 cyl 84 MD9, MY8, M18, 85MD9, MT2, 86-87 MT2. The other cradle (10033670) is listed for all other 85-87 4 cyl and V6 apps not listed for (1000367) above. The other two are the 88 cradles. The only difference in those is that the unique cradle (10042229) for the 4 cyl auto has a uni-mount for the trans that the other 88 cradle (10042231) used for all other engine/trans combos, does not.

I have a 87 Coupe L4 automatic. And eventually I want to install a 3800 II normally aspirated engine, with automatic transmission. Which cradles would fit in my chassis with this configuration? I want to start picking up parts and build it up on the cradle so as to have as clean and easy conversion as possible. I'm thinking with all the conversions that have been done I could fabricate the mounts and even do the exhaust, all prior to the physical install in the car, if possible.

Thanks

Fierobruiser is right on.

To Mr.Chipps: The '86-up 4cyl auto cradles still have the holes for the dual tranny mounts, even though they're setup for the single tranny mount. So if you want to retrofit dual tranny mounts (like for a 3800 install, hint-hint), you can. You can also re-drill the motor mount holes (the holes in the cradle) for a solid motor mount. Here's how.

Just want to make sure I am understanding correctly...
Can use and '85-'87 cradle on an '88 V6?
What mod's will be required?
Thanks!

Don't use an earlier cradle in an 88.
The 88 cradle was redesigned to provide for a complete suspension "makeover". None of your suspension parts will fit, and you don't want to backdate your suspension.

A 4 cylinder 88 cradle will work, as well.
If it came from an automatic car, you may have to grind off the bracket for the goofy uni-mount tranny support. Then again, you might not. Depends on if it's in the way.
