My '53 has a T-5 and a 3.55 limited slip Dana 44 from a '68 GMC 1/2 ton. I think that is far easier than using the closed driveline especially since you wand to change the gears any way. I had to weld on new spring perches and modify a drive shaft. It is also easy when doing this to set the rear wheels in the center of the wheel cut out in the rear fenders. The hardest part is getting the E-brake to work. If you can find the right stuff you can also go to 2 1/2X 11 brakes.
