And with a convertible or deluxe interior (like us) the back seat is even more narrow. Ha, I’m guessing stuffing even a couple of extra-large folks could be a challenge!
Mocking up a stock looking valve cover for either engine, I’ve got a couple sets of these factory style cheater (1/2" taller) covers. Perfect when the low-profile standard height valve covers don't quite clear roller rockers and polylocks. The only issue found so far is that the supplied hardware doesn't fit the stampings, you can't get a socket on the upper row. No biggie, a ¼” flange bolt has a smaller head and does work just fine.
