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.
