Sorry I had posted the I used 9.00 22.5s on my two trucks in fact they are 10.00 22.5s
JPBrecheisen: my 64 is about the same truck you have mine didn't come with RH-5s it had two pice ring tube type 20s though. I bought a new set of wheels they were Accu-rides I am sure same part number you listed sorry to hear they have since been discontinued I bought mine about 9 years ago. Anyway if you can find wheels I highly recommend the swap to the 10.00 20s I will say my truck dose have a pretty potent little small block in it but the size difference should still be beneficial with your 6.
