Does anyone know if a Model A spring will fit on a '35 ford axle, using '28-'34 ford spring perches ?
Go for it. I am going to give it a try. Perch measurements are really close to each other. A's are 37'' and the '35 is at 36 and 9/16".
You will be fine .35 is only about a 1/8 wider than the A axle at the perch holes. 33 to 36 axles are all the same. They didnt widen the perch holes tell 37.
