66 Plymouth Valiant help!

Not to hijack the op's thread but can someone clear it up for me. My slant will remain basically stock so I see no need to change from the 71/4 rear end but would like to have the option of big bolt pattern wheels.I have adapters on it right now to roll around while working on it but would prefer not to drive long term with them.Are there big bolt axles for the 7 1/4 and how available and expensive are they?

There are big bolt pattern 7 1/4 rear axles, but they will not fit the small bolt pattern rear housing. You will need to change the complete housing, or redrill your small bolt pattern axles and drums.
