What would be required to change a 1959 3800 with single rear wheels to dual wheel config? I've read about hub extender for the front wheel, what would be needed in the back? Right now I'm running 8-bolt 9.50x16.5 rims/tires. What would be the best/most common tires/rims to switch to for a duallie?

I have access to a good (older-nothing gets crushed) salvage yard, just need to know what I'm looking for. Thanks for the help!

Can you still call it a barn find if it's your barn?
