Th400 to np205 help
I currently have a 350/350 setup with a 205 case in a 73 k20 and im getting ready to install a 468 with a th400,i understand that there are adapter kits with different shafts needed to mate the 400 and 205 up, but don't know the best one to use as i have seen different types. I also know ill have to modify the driveshafts. Please advise the best route. Should i have my current driveshafts modified or purchase new ones? What is the best way to mate the np205 to the th400?
