(you want that OEM gold certificate.....right? )...30 degrees you might slide by?......in my T/A, I glued the carpet down on them, at the same time I istalled the outer plastic strap guide,.....I think trying to locate them, then glue, then return them back into position you might have problems........think how many seconds the original assy line worker had to install them?
