[Chevelle-List] Seat Belts

[Craig & Cerena Robertson]

I've been in need of seat belts for my 69 SS.  A friend of mine gave me two sets of front seat retractors and belts.  One is from a 67 GM and other from a 70 El Camino.  The silver belt ends are different.  The 67 belt heads are smaller that the one from the 70's car.  Once set I need to return to him.     My question is what year seat belt buckles will fit what retractor belts that I have. I've seen some for sale on ebay but I'm just not sure when GM changed the sizes.  Thanks   Craig 69SS
