I know this has beee a very common mod but my local part stores couldn't be more painful to deal with. I got a set of calipers from O'Riley's, mounted them but are incorrect as the pad does no meet up flush with the top of the rotor. I had bail on them as the 90 yr old counter person was just not getting it. On to NAPA, better guy who gave me this part number SE2152 and SE2151. Anyone know if these are in fact the SW13B casting? i haven't gone down to seen the calipers in person but thought that maybe someone on here may know? Crazy core charge as they are more then the calipers themselves. I also got a reman part number from the local Toyota dealer 477303508084 and 477503508084. The guy could not find a casting number on them but if i order them they are non returnable. I'd prefer to go the OEM way but not knowing if these are in fact correct id rather not gamble the money. Any thoughts from others would be greatly appreciated.
