I have an ‘87 suburban with factory 3 point retractable seatbelts. I’m trying to either replace the whole unit or replace the retractor. I have tried to look for replacements but I can only find lap belts and 3 point conversion belts.
Both front seats have various issues locking up.
I beg you all tell me what grade this dang bolt is? Im going nutso with these bolts. I want to replace them with hex head since the stupid torx bolts suck. I know its metric ( M12) and the thread size is 1.75 but the grade is where im stuck.
