General Discussion / Aftermarket Spring Perches

« on: March 22, 2017, 06:34:42 PM »

I've recently started restoration of my 67 and need to replace the spring perches on the rear axle.  It's a mono-leaf car and I want to return it to it's original configuration, so ordered aftermarket mono-leaf perches.  What I received doesn't fit well at all.  They were made to fit a 3-1/2" o.d. axle tube...not the 3" found on a GM 12 bolt.  Also, the hole pattern doesn't match the GM lower shock plates that I have.  The perch hole pattern is roughly 1/4" wider (left to right) than the GM plate.  I called the vendor and they confirmed that the perches are made to fit a 3-1/2" tube, which I believe the Ford 9" and Dana axles have.  They weren't sure about the bolt pattern issue.  Their lower plates probably match their perches fine, but I wanted to use my original GM plates.

So, does anyone know where I can purchase good quality mono-leaf spring perches for my 67 that fit the 3" tube on a 12 bolt?

Sorry if this has been covered before.  I'm new here and searched but couldn't find anything.  Thanks.
