I agree this is a nice write-up and some good solid pictures.

I have a 1978 C65 453T with the 5 speed Clark transmission. I believe the only difference is I have a tag axle.

I will send you a PM on where I have researched to get the demountable tubeless rims. I believe it's an 8.25 rim width x 22.5 that you will need.
