I converted a M6 crossmember to fit my 4L80. It was a little different in a LT1, but it worked good for about a year, then I got a deal on a BMR one. I still have it lying around. I used some steel and welding to get it to the right length.

I didnt have to delete any "humps" but I'll try to get pics of my crossmember. It's actually just laying there in the corner since I have a BMR one now.
TQ Arm mount was fixed by using a BMR Track Pack and Subframes.

Actually I lied. Sorry. The center of the output shaft is 3 1/2" from the flat on the floor behind the shifter hole were the boot would have mounted.

Im currently fabbing up my own custom crossmember for my 80, I have my car on blocks, I took a measurement from the ground to the CL of the T56 output shaft, and TA CL before removal, and then installed my 80, I jacked the trans up to get the shaft to the same height, then build my mount to hold it at that height. and the same for my TA mount & bracket, This way I am certain I havnt changed my pinion angle, even though I have an adjustable TA I wanted it to be the same as the T56. Ill probably make a post on how I did this as I am taking alot of pictures.
