Yep, I know the feeling about pesky neighbors, too! Ran into the same problem with my 86' F-150. Always sticking their noses over the backyard fence, but when a robbery occurred, they - DIDN'T SEE A THING !! The autopsy tables would work well for wheel covers, especially for the salt flats (Bonneville) and make good teardown/assembly tables (handy drain opening on it). As far as the BB swap, I will measure the engine bay carefully with a mockup to see how much clearance I am dealing with. Best to measure many times and cut once, than the opposite. Thanks for all the great input.
