Two associated occurrences/observations:

In 1954, the optional bed-side spare-tire mount came with a shim for under the spring and over the axle (I think over, not under) - on the passenger's side, I think.

Greg Hill or others will confirm this (from the Factory Assembly Manual)?

I have to decide if I am going to raise the front of my Suburban, because the front-end sits higher than the rear end - it does not look right. Springs are from Eaton Detroit Spring.
