I need info on 67 camaro shoulder harness seat belts and where I might find some to purchase. Also need to know if all 67 have the anchor points for the shoulder harnesses for the front seats built into the roof structure

Yes.

Tom, I remember a couple of lengthy discussions on here about shoulder belts. Click up above on the "search" item and enter "shoulder belts" and you should get some very good information. I seem to remember that Super Chevy Mag did a piece on this very subject within the last year. You might give them a call for the back issue.

my 67 does not have the nut anchor in the roof pillar and I was told from chevy dealer that they didn't get added until aprox mid-year models so you might want to look close - I ended up ordering a new headliner after getting my seatbelts installed. good luck
