Pretty happy, they look like they'll be fairly easy to install. I think what i will do for the high point is drill a hole in the inner wall, tape the nut and two washers to a socket wrench, and extend it really long with a bar or something...then feed the bolt through the hole and try to line it up and thread it in. Think it'll work? I'll let you guys know how I do with this! | | | | | Joined: Oct 2009 Posts: 201 Shop Shark | | Shop Shark Joined: Oct 2009 Posts: 201 | It will work as far as getting the nut on but that sheet metal won't do much more than hold things in place until a crash.
Search around, someone posted a pretty good write up on how they reinforced that mounting point, I think they even did it without a bunch of cutting and welding.
In the event of rear ending someone that point could easily see 500-1000 lbs of load. So design accordingly.
'69 1/2T stepside, Sea Foam Green, 250 L6 w/ 3 on the tree, not an option on it, in the family since new.

I would never just stick a bolt through that thin sheet metal and hope it would actually stay there if I crashed. I'm thinking of reinforcing it even more somehow. | | | | | Joined: Apr 2007 Posts: 456 'Bolter | | 'Bolter Joined: Apr 2007 Posts: 456 | Which belts did you order? I'd like to put a set in my '66.
Thanks, George | | | | | Joined: Nov 2004 Posts: 1,552 Shop Shark | | Shop Shark Joined: Nov 2004 Posts: 1,552 | The backing plates on the seat mounts and the factory seat belts, are rather small and attached to the floor sheet metal. Collectively, they provide the "tear-out" resistance needed, in the event of an accident. A backing plate, similar in size & shape, as the factory seat belt mounting backing plate, is sufficient for the B-pillar on the 3-point belts. The 3-point shoulder/lap belts were an option and the Accessory Installation Manual, indicates the backing plate at the B-pillar. | | | | | Joined: Jun 2009 Posts: 331 Shop Shark | | Shop Shark Joined: Jun 2009 Posts: 331 | The backing plate it came with for the B-pillar is around 3 inches in diameter, so I would think large enough...
George, I ordered them from a company called Scott's Super Trucks here in Alberta Canada. Where they get them from, I'm not too sure. Pretty sure they came from the States. If I recall, the box they came in said "The Truck Stop" or something. I'll have to look tomorrow. | | | | | Joined: Oct 2007 Posts: 725 Shop Shark | | Shop Shark Joined: Oct 2007 Posts: 725 | I got my shoulder belts from www.seatbeltplanet.com. Good prices, fast shipping and the guy who answered walked me through my order. They're easy to install, too.
