Leaf spring perch install

[Billw69]

I’m replacing the spring perches on my B1, wondering if their surface should be parallel to the pinion angle or do I need to include some angle? Seems to me that parallel with the pinion would allow the use of shims to accommodate driveline geometry? Suggestions.

Thanks

If it was me I would locate the perches so that no shims were needed to get the desired pinion angle.

Makes sense. I looked over an axle out of a ‘71 staggered shock car today at a friends shop. Using a magnetic angle finder I was able to determine the perch’s have an approx. 10-11 degree difference from the pinion angle. This makes sense knowing the leaf springs are not level at the attach point of the perches due to the arc of the leaves .
