Difference in Axles

What is different about the C-20 rear axle compared to the C-30 dually axle besides the obvious extra set of wheels? I'm looking to convert my truck over to a dually and are looking for the most cost effective way of accomplishing that with minimal modification.

Re: Difference in Axles

Typically a C30 would have had bigger brakes. But as long as your wheel studs are long enough, and are the correct diameter for the correct nuts for the dually wheels, they should bolt up to a C20 rear end. I would assume it is your '63 C20 you are inquiring about?

It is my 63 C-20 I'm inquiring about. Here is a pic of my right rear hub taken with my phone.
