that block number does read as a 58-62 ..... not sure how/why the bell housing would have been modified other than cutting off the mounting ears, but it's common for a lot of years .... for that price I'd want a money back guarantee, it'd cost more to have one rebuilt, but you'd be more certain of what was done, who did it, and if it's still good after sitting however long
note you'll also need some original front mounts [available repro] or an aftermarket crossmember to put it in the 'burb, as well as a rad shroud
