Thank you I will search for it today or tomorrow I will find oneWelcome!
Search for 1:18 AXLE and you should get results for a 1/9th scale and you'll have to do some math depending on which drag racing rear end you plan to replicate.
I've got numerous 1/16th scale kits both drag racing and bone stock cars, but none are Pro Modifieds. I can measure the 1964-1/2 stock mustang rear axle, but you'll still need some math. I've got a couple ford 1/16th stock cars but that's the best I can do for a mustang.
Maybe someone else will chime in?
