Three point seatbelts
Since I'm waiting on some bolts to come in to finish the frame, I started looking closely at the cab. I am making notes for all the holes I have to weld up.
I found a couple of small rust holes on the rear corners, just above where the two metal factory mud flaps were installed. The mud flaps are still in very good shape, no rust. While making notes, I started trying to set up the 3-point seatbelt for installation. I was looking for a couple of things. 1. Does anyone have the measurements from the inside of the door frame to the first bracket on the floor? 2. A measurement for the second bracket? 3. Pictures of your installed so I can see where you put them. 4. Has anyone done a 3-point? I've seen 2 YouTubes on that subject, and I'm just not sure about the way it was done. If you can help, thanks.

Re: Three point seatbelts
I used 2005ish sierra seats with integral belts. Seats bolted to floor with 4x4 plates sandwiching floor (rounded corners, bent back edges Gr8 bolts)
I'm happy/comfortable but I know these seats are not everyone's cup of tea. Locations; Do you have your seat and steering wheel installed? I'd get comfortably located in the driving position and place the belt attachment locations relative to my body using some modern daily drivers as a reference and paying more attention to the angles than the distances. I'm not familiar enough with the TF cab to give specifics, but for the 3rd point you are going to need to get a large plate with a nut for the belt attachment welded to the back of it up inside the inner skin of cab in the area of the pillar and plug welded into place. -maybe- glued in place if you have a finished interior, the important thing is that it stays where you need it and has a large enough surface area to stay behind the sheet metal in a crash. |
