Re: Axle swap problem

Proper axle width is measured from wheel mount to wheel mount. Measuring to the back plate is not correct. Not all back plates are the same, most are, but not all.

My 1970 GMC 6 lug GM12 bolt leaf spring truck had the wider axle. The width is exactly the same as my 1972 Chevy 5 lug coil spring truck.

My 69 D-60 6 lug leaf spring axle is narrower.
