M21 rigid - hub offsets

[berniej]

I'm rebuilding a '57 M21 rigid and could use some help with the hub/rim offsets please.

The rear is a Type 10 with the riveted hub and the front is the Type 5, 8" half width with alloy plate.

I will also test-assemble the hubs and measure to the frame C/L but some actual offset figures would be very useful.

Thanks,
Bernie
