Help! 1969 Nova Multi-Leaf Spring Perch Width?

[WILMASBOYL78]

I don't often chime in on technical issues..because there are so many gurus who have more knowledge....but, since I had a 12 bolt housing sitting in the garage with new spring perches plus a 69 car with springs installed to measure...I figured..why not contribute.

The springs are indeed 2 1/2" wide...but the opening in the spring perch is almost 2 7/8" wide...when the spring is installed the rubber mount surrounds the spring on each side, so you need additional width in the spring perch for it all to fit. I would say the rubber on each side is at least 1/8" - 3/16" thick...so the larger width is probably correct.

Hope this helps...wilma
