I bought these years ago and never used them. Never even tried to see if they fit.
These are all the brackets you need along with new rubber mounts for a 3800/SC & 4T65E swap. The trans brackets are from a Trans Sport Van and the motor mount is from West Coast Fiero. When using the Transport mounts you will need to notch the cradle slightly as these mount the transmission lower than most aftermarket brackets. $200 plus shipping for all of the mounts.

Nice deal but to clarify on this setup; The engine mounts/brackets will fit but the trans brackets will only fit the left side of 4T65eHD up until 2002. The 03--07 4T65eHD transmissions dont have two mounting bosses to bolt on the right side bracket. The WCF bracket picks up on an open hole on the bell housing on the later model years..

The 1989 3800 was a series 1 design. The supercharged version only made 205 HP. Not sure if the mounts shown here would work on the series 1 engine but that engine would be over 35 years old, and IMO not the best swap.------------------

I'm interested. I have a 2002 GTP motor trans and 86 gt so it should work. How do these mounts hold up on stock power and if one goes are replacements available? Is there a dog bone mount that works or will i have to fab one?
Thanks

I would suggest a dog bone mount or even two on the 3800SC install.
This how the the first swap install looked after completion. Later on the WCF dog bone mount was added to the transmission side and Fierorog s tensioner bracket with dog bone mount was added to the stock side. We've used two dog bone mounts on all the swaps since. . The grand Prix 3800's has two mounts so why not the Fiero .

Since I never installed these, thank you Dennis for the input.
