['68OrangeSunshine]

I've been lucky with both the '68 C/10 292/SM465 and '71 Jimmy 350/SM465/NP205 because the bellhousings have 3 parallel bores and my starters bolt up w/o shimming. In fact the front plate of the flywheel pan is bolted-thru so it's a big shim.

I am unfamiliar with the drivetrain you're running on WMB. Looks like automatic transmissions are involved.

That seems pretty squirrelly of NAPA to fudge on your warranty. Most of my ''Lifetime'' warranties were with Checker Auto. When O'Reilly bought them out, they promised to honor existing warranties.
Yeah. Sure. The majority of warranty replacement parts, Dimmer Footswitches, EVRs, Alternators, have been duds. I've been cannibalizing off White Fang for good late '90s or OEM vintage parts.
They did ''buy out'' my warranty on the P/S Gear for my '71 GMC K/1500 Jimmy at about $350 in cash. Then I had to buy a UFO* from RockAuto.
I kept about a hundred. When that P/S Gear goes bad, I'll have to go on the hunt again.
