The Ford Top Cover 4-speed, found in 66 and newer Fords, is the best 4-speed available for all-around driving. The way to spot this trans is by it’s 10 bolt top cover. The small block 4-speed from a 289/302 with a 2.78:1 1st gear is the best choice. This kit comes with a new main shaft splined to accept the stock sleeve in the transfer case, seals, gaskets and a special bushing to be installed in your stock V8 3-speed tail section, which requires minor modification. Crossmember doesn’t need to be relocated and the 3-speed clutch linkage can be kept. Our OLD (discontinued) #2101 4-speed shifter is needed to complete the job.
