we sold the force 5 bogarts to Dave Young for his 63 and Gene Mosbeck for his 64 and I'M pretty sure John Dinkle as well they were all 15X 10 and had a 5 inch BS.

I had 10 inch with 4 1/2 BS 64 Ply. With 65 rear end with no Key axles.
Wider/ Later Rear End will require more BS. What year rear end are you
using and what width and I can tell you more exactly?

Most everybody who ran these cars replaced the weak and difficult to remove
Keyed axles with a later model rear. Many years had the same spring perch
width ( about 44 inches ) but differing widths of housings affecting the back spacing
choice.

You should have some leeway because we used to run 10.5 width in SS without any
mods except wheel lip.
