I found out my car has the original deluxe seatbelts in it, but turned out that I was missing the passenger side retractable one. Anyone know where I could locate a correct 67 dated black replacement? I pulled a blue one from my parts car and it fits, but not sure if I can dye the blue one black or not.

Also, I learned about deluxe belts this morning. I might have a full set of '67 blue deluxe belts if anyone has a set of black they might be interested in switching? I'll have to double check first, but pretty sure about it since this blue one plugs into my black set.

I have the deluxe belts too in my 72. They're hard to find. Here's a site that will sell you the buckle itself.http://www.andoauto.com/hardware.htm
You can get the retractors and covers at Year One, I think. Also, check Andover restraints. You'll have to get an upholsterer to sew the belts together for you.
Here's what I did: I took my belts apart and cleaned them. Then, I bought new belt webbing (mine was dry-rotting). I took the webbing and put the belts together and used an office stapler to staple the belts in place. Then, all the upholsterer had to do was sew where I stapled. It cut his time down considerably, and therefore my cost. Good luck.
