Did you speak with a young buck on his computer at your local NAPA or an old boy who knows how to use his old catalogs and parts books?
This can make a huge difference. Those veterans are pretty crafty at finding those elusive, “obsolete”, can’t find ‘em, parts.
My guy’s name is Doug. He’s good.
For sure the veteran parts people are great at finding the stuff in the books.
Rant, Recently went to AutoZone and Oreilly's to get brake hoses. Granted I have a unique setup now because of the front disc conversion, but the hoses are stock hoses. I figured out the year I needed, they showed they were in stock, and this was at both stores, each kid walked around the back for 10 minutes searching for the elusive items. They couldn't find them. I left and went back to AutoZone about an hour later, got the manager, he got the rolling stairs, rolled them over, climbed up, pulled out the bin, and grabbed the hoses. Unfortunately they both didn't have the correct copper washers, one was correct, the other was metric, and they don't have a box of them, only the packs of various sizes so you end up with a bunch copper washers you'll never use. I said no sale because of the washers.
