Hi Cliff and Andrew
Which truck are you speaking of year and size? I understand that you are talking about the Chev front ends used on Fords, from your picture Cliff it looks like a C30 or F30 or possibly C60 or F60 with the small brake drums but what size are the wheels?
What confuses me though is my `41 Chevy Pat 12 C60L has the small drums with originally 16 inch wheels. That housing has the separate front covers and doesn't have all the reinforced areas I'm seeing in your photos.
