For certain, the ones out of the Firebird and such from GM are not strong enough for our cars if pushing over 300lb/ft of torque.
I know for sure that it will fit as I have ridden in a 91 T-bird with a T-56. There is a guy that doesn't post much on any MN12 based forums that lives in Rome, GA that converted his 5.0 car to a hydraulic setup T-5, then turned around a couple years later and put in the T-56. The car is wicked as hell too as it has a 331 twin turbo setup to go with the 6 speed. I could ask him to do a writeup about the conversion....
I don't know where these ideas come from. Stock LT1's made over 300ftlbs torque. The transmissions being referred to here might not stand up to 5500rpm clutch dumps, but neither will your axles. I would have no reservations about putting one in my car. They are stronger than an M5R2.
Was looking through a bunch of downloads and printouts here are a couple of tid bits.
Here are the McLeod parts recommended by Billy M (Tech advisor @ McLeod)
260571 is a 26 spline 11" disc for the LS1 T-56.
361954 P/P (going to use the Sach's I have <2000 miles)
P20810 Pressure Plate Shim.
No you do not need to change your slave. (changed same time as P/P)
Haven't found anyone with the shim or any info about it.
This may actually be easier than it sounds?

T-56 Swap into 1993 SC (originally w/M5R2)
1993 3.8 SC engine w/138K (under a minor rebuild)
2000 LS1 Camaro T-56 6 speed trans
McLeod Belhousing Kit 8750-06(SBF/LS1 adaption)
Original Ford flywheel
McLeod Clutch disk 260571 1-1/8"x26spline (with a reverse button)
Sach's (OEM replacement SC w/M5R2) Pressure plate and slave
Hurst Billit Plus shifter (2000 Cam., no knob yet, probally mod the stick any way)
The pilot shaft goes in deep to the recess of crank (splines do not restrict) only about 1/4" of splines go in. (if this was going into a Hi HP setup AND I had the $$ might have a custom input shaft done with the pilot end made to fit the M5R2 pilot bearing vs using the bushing that is not very thick (maybe 3/8") (i.e. if I ever get to do a BBF/T56(LS1)-Bird -McLeod belhousing P/N 8746-06)
Measurements indicate the shifter is about 1" forward of stock position and the trans mount is about 1" farther back than stock. Also that the end of the output shaft is about 1" maybe a tad more towards the front (therefore needing a longer driveshaft)
Hope this is a little clearer.

For the slave and throwout bearing McLeod makes a slip-on/over-the-snout slave actuator with integral throwout bearing. This slave literally slips over the T56 input shaft and remains sandwiched between the pressure plate and transmission (read: no throw out fork required) within the bell housing. It also incorporates a bleed line for system bleeding (I'll bet this got your attention) and an internal adjustment collar which is used to move the slave closer to the pressure plate if needed. The slave is all metal, and rebuildable (o-rings). The actual throwout bearing also slips onto the slave cylinder and it too is replaceable. This slave has a stoke of ~ 0.650"; you need about 0.250" to release a clutch disk.
