[rexs73gto]

Not sure if this is the right place to ask but I hope 1 of you guys can answer this for me. I want to know if I can put a T-5 in my 73GTO. I now have an M-22 in my 73 GTO & it's been in there for about 35 years. I want to be able to drive it again long distance but with the gears in it right now it makes it almost impossible. I have 3:73's in the rear & it get about 10-12 mpg. Plus on the hwy. I have to keep it down to about 55-60 mph or the MPG. goes down even more & it get hot quicker when I stop of course because it's been running hard, about 3200 rpm's for that speed. Hard on the engine to. I want to know if I can do a direct swap with the T-5 & M-22. I ask can I just pull out the M-22 & put in the T-5 with no other changes, or do I have to go to a HYD. throw out bearing & a different P/P. I know I'll have to modify my tunnel a little to have the shifter come up through the floor, but do I have to change a lot of the other items listed. ??? Any help you can give me will help. Also which trans do I look for ???
