I'm planning to replace the 2-speed powerglide in my 69 with a 3-speed 350 turbo transmission. I know I will have to change the torque converter but will I have to replace the flywheel, crossmember or driveshaft? Also, do the fluid lines have a different bend? Anything else major that will need changed? My car originally came with a 350 turbo so the stock shifter is already set-up for one.
