Only one thing missing from this thread to be a compleat swap thread also is the information on the CV shafts needed to use the 4T60E.
Hint Hint anyone, Sanderson?

EDit to add:

I found this info on FieroAddiction's site. Quoteing from his site, I hope he doesn't mind, any credit goes to him for the information:

"For a 4T60E you can use the same left axle for a '89 Pontiac 6000 with 4T60 and light duty brakes on the left side, and a left axle for a manual Fiero on the right side. Some people have reported having problems with the Fiero axle on the right side, but they have always worked well for me."

I used the '89 Pontiac 6000 axle on the left. On the right I used a 92 Old Silhouette with 4 speed auto and swapped a Fiero manual CV joint on the outer end.

Which side of the 92 Old Silhouette did you get the parts from?

4T60E Axles

I found an archived thread from 2004 by member jeffndebrus that details how to get the correct size axles for a 4T60E. He also has several good pictures of these axels, and a good "how to" swap out the one hub end. I quote from his posting.
Drivers,Left, side:
"For your drivers side of the Fiero with 4t60e you can use a left axle for a '90 Pontiac 6000 with 4T60 and light duty brakes. It is a stock drop in part and works well."
Passenger, right, side:
"For the passenger side you have to use a GM axle part number 9572 which can be ordered by asking for a 1994 Pontiac Transport van right hand axle-4spd automatic 3800.
The outer CV joint on this unit is too large to fit the Fiero hub/bearing assembly so it must be removed and exchanged for a Manual Tranny Fiero CV joint.
***Please Be Advised*** some axle remanufactureres are using smaller diameter axles so when you get your Fiero manual cv joint---make sure that the axle which it came off of is a 1.030in axle---NOT the smaller .85in which some are using.-the smaller cv joint will not fit on the minivan axle."

Excellent post. Really good info here. The only thing missing were suggestions on what size serpentine belt to use and what fuel pump you ended up using.

Good point on the fuel pump - will add that.

As for the belt size, I can add that too, but this all depends on a number of factors (a/c compressor in the loop, the idler below the alternator, water pump idler size, etc).

Anyways, original post updated - thanks for pointing that out.

BTW - I left out the axle info out of the original post as others have replied on what to use (and I never done one myself). So thanks to josef644 and sanderson for the info.

I believe the left side axle needs to come from an '89 Pontiac 6000. When I got mine from Carquest they didn't list a light duty brakes option for '90.

It's a tight squeeze but I did manage to get the OEM Cadillac fuel pump into the tank.

As you point out the belt length will vary depending on the details of the belt routing. I've got the Camaro tensioner with A/C and I'm running a 79" belt. It's a tight fit. I actually have to unbolt one side of the tensioner to get the belt on. But with a 79.5" belt it felt like the tensioner was fully extended.

I went to RockAuto and looked up the fuel pump for a 1993 Deville, and a 1988 Fiero GT. Both used the AC Delco EP378 fuel pump, $78.79. 1987 Fiero Gt used a different one, EP240,$80.79. Two bucks difference. I was thinking that the 87 and 88 Fiero' both had the same enlarged just a bit fuel tank. I would think the FP access hole has to be the same.
