31 Slant W/S sedan rear bumpers
 

What size risers are required on the brackets, 4-1/2" or 5-1/4" ?
Thanks, Mark

Our SW measures 5 1/4" from top to hole center. Better get some others' input also because I've seen a different spec but can't locate the source.

Marco has a diagram that shows all rear bumpers dimensions
I’ll try to post it in a few days when I get to a desktop
Also one could go to Marco’s Barnyard it should be there

on my 160A the stand is 4 3/4" from the top to the center of the rivet. like Bill said you want to make sure you have the correct rear bumper irons. they are longer then most other Model A`s

As JW stated longer and they are more curved also.
