My B has a single big nut rear axle. What do I need to do to swap it for a five bolt axle? I have a donor B with 5 bolt axle, do I swap the entire final drive assembly?

That is the best way to do it as far as I'm concerned. I've tried just swapping the axels & that was a BAD plan! Kip

The easy way and probably the best way to get where you want to go is swap the complete finals.

Another method is finding a good set of 5 stud wheel adapter splined hubs B part number 210318 and use them with the 5 hole B reversable wheels part number 210105.

The adapter hub replaces the splined wheel center and you use the same big nut and washer.

The bolt circle is the same as the B flanged axle used with the reversable deep dish B/C wheel Part number 210214

The reason Bs had the 3 wheel options was to allow a wide range of rear tread widths from 40 inches up to 68 inches

Is the C 5 bolt centers the same as the B 5 bolt centers? As I have some C inner wheel weights that I would like to use when I do the swap?

I've got a B with the 5 bolt rears and adjustable WFE. It has the C weights on the inside rear wheels. Mike

Mike;

Pretty much the same thing I'm doing, swapped the arch for a adjustable front end already, and now came across a B with 5 bolt rears and I already have the C inner wheel weights, and more options at rims widths with the conversion is a plus.
