OK, good news, bad news. They are 2292s, but they are still in the block & look to be very stuck. I picked this up years & years ago just for the fairlane motor mounts attached to it. it had a spun bearing & that piston was already missing. Got one out back then & that one has some scuffing on the very bottom of the skirt. Probably ok to use in the opposite bank or lightly knurl it. I'll kroil it over the weekend & see if I can get something loose.
