The Hurst boxes are all fairly similar and would fit the stock bracket on the truck, as well as A, B, E bodies and such. There are minor diferences in the levers where the shift rods attach on some models, but there is usually plenty of adjustment in the shift rods to get it hooked up.

Now, here is where your going to get into a little trouble. The stock shifter stick is a slide in deal. Now, you can make your stick a bolt on style for the comp plus shifter by drilling the holes out (what I did to the stock shifter and stick to take the slop out of the cushined retainer). If I remeber right, the dimples are in the stick so you know where to drill it, so it is really easy IMO to do.
