87 and a 4t65e-hd with Roger’s mounts The 3800 axle is way too long and I put together last night a manual driver’s axle and it’s questionable on the depth of the tripod
Is there any axle that’s a medium between these two??
been a very long time since I did my auto swap, but the passenger side needs to be a Frankenstein'd pretty sure I used the donor (grandprix) drivers side axle.
So it goes something like: Fiero outer >> GP Passenger outer cage and bearings >> GP Drivers Axle >> GP Drivers tripod & bearings
don't hold me to it though

I've done a few automatic swaps and reusing the driver side 4T65eHD axle bar on the passenger side with the Fiero tripot and tripod hasn't worked. The mounts that I used more closely centered the powertrain. The axle proved about 1" -2" too long. The swaps used the same size axle on both trans sides. Its been a while but IIRC it was from a Pontiac 6000. Measure up and go online to get the right side axle.

I read back in a post that 1993 Pontiac Transport axle works too

My error the 6000 axle was used on my 4.9L swap Correcttion
These are drivers side axles compressed length:
1995 Beretta 20 1/4" (both sides) Manual or auto 02-04 Cavalier 3800 auto or manual 21 3/16" (both sides) 1998 Lumina auto 20 3/8" 1995 Transport Van auto 20 1/4" The Grand prix 3800 driver side axle that you are trying to use is 21 7/8" compressed. Just use the Transport or Beretta and your should be OK. Its most likely direct fit

That’s awesome. Those are the measurements I really needed Thanks Dennis 👍👍👍👍

I`m having a problem on the passenger side. I got axles with a set-up 3800 already on the cradle. The trans, I believe from what I have read is a non-hd as it has no roller bearings in the diff end. I believe the mounts used maybe from WCF but I`m not sure where the axles came from. The one on the drivers side looks like it will work ok but the one on the passenger side it fits into the diff and it fits into the Fiero hub. The problem seems to be it`s just a bit too long. Basically, if I compressed it all of the way it may fit between the diff and the back face of the knuckle but I don`t think there would be any play. When you level suspension (88) with the axle in line with the diff (being in it`s most compressed state, how much play should it have? In other words if I pull the knuckle out, install the axle and slide the hub over the splined part of the axle but not install the nut how much play should the axle have when pushed toward the diff. I would think at least maybe 1/2"
