So I grabbed a pair of centerbolt valve covers that I had on hand, to fancy up an engine that I'm gonna drop into my '90 Suburban. With just a quick comparison to the intended recipient, they appeared to be an exact match. I sanded them up and painted them a nice, gloss red... Imagine my surprise when I went to install them and found out that the "centerbolts" are NOT in the center of the cover. They're offset ever so slightly to one side, meaning that they can ONLY be installed one way. Of course, the PCV and oil fill holes are at the exact opposite ends from where I need them to be. These appear to have come from a Caprice, so now I'll be painting a set of truck covers. Anyone need some spiffy covers for their car?
