help on swap
I see them going for 5-800 here in Seattle but you have to take the whole motorhome.... for 800 if you don't have to take the whole thing, that is a bonus!
727 out of an RV may have the park brake on the tailshaft and a bolt-on flange on the front of the drive shaft instead of the slip-yoke. You will want a 727 out of a car along with the driveshaft (or at least the front part of it)
