I am converting an auto 2.8 1988 fiero to a 3.4 with 5 speed getrag. Wheres the place to get manuel Drive axles? Is there anything I need to do for the conversion? New flywheel?
What all do you already have?
You will have to get the following: clutch pedal and brake pedal set. Master cylinder and slave cylinder. Fluid line. Shifter assembly and interior surround. Shift cables. ECM. Steering column for a manual or adapt yours. Adapt the engine harness. Axels for the trans.
For the engine harness, you will have to extend the VSS wires. The reverse light switch on the automatic is right there by the gear selector. You'll need a pigtail to plug it into the Getrag reverse light switch. The Getrag switch is right there on the tranny, near the shift/select arms.
The big yellow wire is the "start" wire. It changes to purple on the other side of the P/N switch. I just ran the yellow wire to the starter when I converted mine.
Swapping to a manual harness is another option, but you'll have to move the "start" wire in one side of the C500 connector. (The one above the battery.)
Both of these scenarios will do away with any sort of interlock. Meaning your car will be able to be started in gear. You can add the switch to the clutch pedal if you want. I can't recommend that you do otherwise, although I skipped this step on my build. I also retained the automatic column, but I removed the cable that allows it to lock the shifter.
The other "gotcha" is that if you have a trunk popper, it will work at all times. Normally there is an interlock for that, too.
You asked about the flywheel. You'll need a manual 88 Fiero flywheel. Or one from an 89 - early 90s 3.1 Beretta (or similar) with a manual tranny. They're all similar.

The automatic will have a cable coming from the shifter that allows you to lock the steering column when the car is put in park, the standard has a manual switch. You can disable the switch if you don't want to swap parts in the steering column, but you will be able to turn the key back to the lock position at any time, including when the car is moving, which was the purpose of the switch in the first place.
