Yep, has the shoulder belt anchor but they are the detachable shoulder belts. At least I don't have to build an anchor in the roof.
1974 was the first year for fully retractable seatbelts, but was kind of clunky in their application due to a ratcheting mechanism. 1975 was better as they went to an inertia mechanism, and it is a bolt-in to a 1974. At least, as I understand it.
Thanks!
Perfect.
Started working on trying to buy the '73 so unless the deal falls through I will almost certainly have to do something like this.
