9" rear in a jailbar truck

[TomT/Williamsburg]

I think it is a great idea - with parts, brake shoes, and the complexity of changing anything in a banjo rear, it really is a no-brainer, 9 or 8”. There are more readily available junk yard pumpkin gearsets for the 9 vs 8” rears so 9” overkill - yes - practicality the 9” is a clear winner in my book. Oh - if you are running a 5.5” bolt pattern go 9”.
Go for it!
