Hello, I have a buick GS STAGE 1 455 4 SPEED, I am in the process of turning it in into a road race car. I want to remove the four speed and put in a wide ratio 5 speed? are there five speed kits for the GS?
You will have to make your own fit. For example, I think all 5 speeds would require a custom modification of the drive tunnel , drive shaft, maybe the cross member location, speedo drive, etc. I doubt any provide for the TCS. From just a finacial standpoint it may be worth considering modifying a skylark rather than cutting up such a rare car.
