Pistol Grip shifter handle, what else do I need?

Which B-body shifter did you get? There is a '70 non-console, a '70 console, and a '71-'74. You can get new rods from Brewer's Performance for $140, or you can make your own if you can find some donor rods to cut up. Somewhere around here there is a thread about putting pistol grips in A-bodies.
