Lawrence -- I've replaced all three of my 240 ps/ac systems with non-ac setups. These are my '81, 83, and 87. Early 240s often came through with non-a.c. In this situation, there's a different plate which bolts to the block. It mounts the ps pump a tad farther forward so the pulley is driven by a belt off the crank directly. It's been two years since I did my most recent conversion, but I believe the new plate mounts with a threaded hole which would otherwise have been unused. So there's one new bolt hole with good threads. But I believe it still uses two other bolt holes. If both of them are stripped on your block, I wonder if you'd be able to get a helicoil spun into them. I've had no experience with this, but I understand this isn't an uncommon practice on stripped spark plug holes in the cylinder head. You could drive your car with the ps pump removed (it'll take some muscle, but it's doable) to a machinist to get this installed, then you're all set.

If you cruise the pick-n-pulls regularly, you'll sooner or later come across the non-ac ps pump setup on a late 70s early 80s 240. Grab everything -- it takes different ps pump mounting straps and different bolts; little is transferable from your current a.c-equipped ps setup.
