I am restoring a 68 convertible for a friend of mine. I'm putting the original shifter back in, the bracket is on the way from Corvette Central. The bracket for attaching the Hurst shifter the car came with looks relatively simple to remove. However, the original bracket looks quite a bit larger (only have pictures from google to go by). What will installing it entail? Will I have to unbolt the transmission and lower it? Thanks in advance.
