The only problems with just hauling off and changing the rear end are listed
below. This is something I will be faced with very soon and am NOT looking
forward to at all.

1) Lug Nut Pattern... good luck finding a modern 6 lug pattern.. so now you
either get to carry two spare tires so you can change a front one, or.. make
an adapter plate for the rear.

2) Braking system...good luck again trying to get your hucks brakes on the
front to work with the modern rear. I hear a proportioning valve will be
needed at least. I am not sure if this is a big deal or not.

3) Welding Perches.. suggest being really good at welding since these are
pretty crucial to be done by a professional or at least someone who knows
what they are doing. Lots of load bearing on these welds.

4) Drive Shaft.. You might get real lucky and find a driveshaft that is the
proper length. Probably not, so there is the expense of a custom driveshaft.

I am sure I have missed a few things as I am getting more and more nervous
about doing this. My plan at this point is to use a 55 1st series rear end.
Perches should already be fine, its 6 lug already, and there is a slight
chance of putting either all bendix brakes on it, or all hucks depending on
the difficulty of borrowing from the donor.
