I currently have a powerglide (original)in my 67 SS396 & want to switch to a Turbo 350 ("short" tailstock with torque conv.) that I have. I've seen the replacement console shift indicators, so it looks like it should work. What all will I need to change to get the Turbo to install & work? Crossmember? Driveshaft? Shift linkage/shifter? Speedo connection? Any help/suggestions would be greatly appreciated!!!
