Re: New to the board. Have a 1964 C20. Pics here.

Beautiful truck, and welcome to the full floating axle club! Really glad you aren't going to give it the El Camino treatment.

Also, you might consider just a 4.10 third member and tall drive tires. (I think those are 245/75 tires you have now?) My truck has a 283, 33.5" tires, and a 4.10. It runs about 2,150RPM @ 50MPH. With shorter 235/85R16 radials it should still be around 2,250RPM at the same. You should be able to come up with a 4.10 third member for $100-200, and you don't even need to jack the truck up to change it.
