I want to swap rear ends. There seems to be a few differences. One in particular is the spring mounts. On the 49, the axle mounts above the springs, while the axle for the 77 is mounted underneath the springs. How do I get around this? I want to leave the original springs in the 49. Or do I have to change them? If anyones knows where there is info on this, or any help would be greatly appreciated. Thanks.

I've seen a 47-53 rear end conversion kit, but I think you need to get new leafs too. If you are getting rid of any parts on your old rear end, I may be willing to make it worth your time.

just make shure you take a lot of measurments to align it corectly. | | |

Been doing some reading. One thing I read says I have to make sure my pinion angle is correct. What exactly does he mean? And how do you calculate the angle?
Also. When I took the 49 rear end out, I broke the bolts that go through the center of the springs. Can those be changed?
ysrjunkie. I certainly will keep you in mind when I get it done. Are you in need of any other parts? When I bought the truck, it came with new drums and cylinders and parts for the huck system. I am upgrading to discs in the front so I won't be needing the hucks. Thanks.

For the pinion angle I used a adjustable meter for measuring horisontal surfaces(don`t know the english word) on a flat surface next to the pinion
and made sure the mounts were horisontaly.
The most importante thing is to make shure the axle does not go straight in, you want some movement in the x bearing between rear axle and axle from engine. | | |
