I have a 3800SC Series II motor with the 4t65e-HD transmission. I was wondering what axles someone else is using or fabricated for this swap?

-Brian

Also interested in seeing what other people did for axles in other variations.

Youll find in there I talk a lot about beretta axels, but in the end I found that 04 cavalier axles are a little longer and made me feel a little safer. Its not just 04 cavy, all the J body cars of that series have the same axels. They use the same axel both driver and passenger, so it doesnt matter, just get 2 of them.

I have the parts to make the Automatic passenger side axle (new).But you need the OEM axle end off the Fiero,to combine them into one.Send me a PM if interested (reasonable price).3800SC series II Automatic.

send me a PM if you plan to build your own,youll have a few less problems.

Be sure when you go to get your axles that you dont buy aftermarket axles. Alot of them are smaller in size and do not work out. Alot have found this out the $$$ way.

J body axles are exactly 1" OD. Fiero stock are .9"

For the J body axels, you dont need any Fiero parts, just the inner joints from the 4T65eHD, the joints that go into the transmission.

After trying several of the formulas posted on this forum and not achieving the right fit I turned to the professionals. The reason that there is no universal axle fit for the auto swaps is because all swaps seem to have a side to side mounting variance of 1 " or more. WCF, Purple reign and custom mounts all seem to place the engine in a slightly different position. We measured positions on several 3800 swaps and they were all different.
The axles on my 3800SC auto swap were custom made by an axle shop. They use the GTP inner tripots, Fieros outer tripots and both GTP tripods. I am not sure what axles are used. We just held the control arm at road position and measured from the end of the outer tripods to the center of the inner tripot, gave the measurement to the axle shop and they did the rest. My axles now have a factory fit.
