The clutch is the same. If you are using a driveshaft with a center bearing (2 piece), you can get rid of the slip yoke at the tranny end as long as the axle end of the driveshaft has a telescoping section. Just pop the U-joint out of the slip joint and install it in the yoke of the 4 speed transmission. If you have a one-piece driveshaft (no center bearing) get a telescoping one.
You could switch to a 4 speed Saginaw and use the slip yoke driveshaft if you don't care about having a granny first.
