i didn't realize their were numbers hidden, i'm a newbie at this, maybe i should go with skins as opposed to full quarters? they really are only bad at the bottoms,a few inches or so, thanks for the tips, here is the engine i have found, it shows E440, dated to '69...253643010 that translates to an RB440, any ideas if this is a good one to rebuild? and any books on "dummies guide to rebuilding" lol, HELP?
