My 4sp swap thread

I think that the only difference in the hump is that you have to add a small piece of metal to the 75-76 4 speed hump when installing it into 67-74 year A-body cars. On the trans it would be more of what you are wanting to do with the car. If i was wanting to do alot of highway/ interstate cruising with 3.91 gears I would go with the OD A833. If not and more around town is what you have on your mind and not to much long cruising over 50-55 mph then a regular 4 speed will be fine. Also on a diaphram style clutch like the centerforce I think you are supposed to remove the overcenter spring on the clutch pedal set.
You could also call brewers performance and talk with them as well.
Hope that helps, Matt
