Jerry’s comment about two different cap heights covering nearly all domestic vehicles is helpful context.
If that’s the case, it would seem that the taller of the two variants has quite a range of actual listed heights: 1-1/16” to 1-1/2.” The cap I bought is allegedly 1-1/16.” I’m not sure how how/where they measure from as that number doesn’t correlate very well with anything when I put a ruler on it.
The short variety is more consistently listed at 3/4.” I’ll try one of those.
