I assume some of you may have upgraded your seatbelts at some point to a newer style of belt. I've actually never seen any belts like the stock ones in my 75, where the shoulder piece is rigid and doesn't retract - you shoulda seen the confused look on my face when trying to set my seatbelt for the first time, lol. Anyways, the PO gave me a set of newer "modern-style" seatbelts that I want to install in the truck since there's none on the passenger side right now. I'm pretty sure the new ones are out of the 78 parts truck he stripped. I went to bolt in these new units but found that the older truck doesn't have a hole for the protruding tab on the back-side of the retractor base. The tab keeps the retractor in vertical position. Since my cab interior is freshly painted by the PO I'm on the fence about drilling a hole for the tab or cutting off the tab so the base can move freely like the original 75 belt is currently. Wondering if there will be any functionality lost if I remove the tab? If I go that route I'd likely put some felt bumpers on the back-side so it can't scratch the paint. What did you do on your trucks?
