I'm in the process of installing inertia-reel seatbelts for the middle row of my 110. Judging by the existing mounts, it looks like my truck had static belts installed at some point, however, some of the mounts and whatnot are gone.
I think I've got everything worked out to install the reel and buckle assemblies on the door posts, but I'm having an issue with the floor mounted buckles. As you can see in the photo, the only thing I have left are two holes in the floor. Judging by the marks left in the paint, it looks like it simply had stalks mounted similar to front seat belts. I've ordered part # RTC6065 (see photos and diagram), and need to insall these. Now, I understand how to install the plates with the welded tubes. These are the parts that the seat belt assemly mounting bolt will thread into. However, what is the other larger plate for, and where does it go exactly?
I'd really appreciate if someone could post a photo of what their mounts look like, both from inside the truck, and from underneath so I can get an idea of how to install these parts.
As it is, I'm going to have a bit of an issue, as the proper tub crossmember has been replaced with some home-made crossmember, and I don't think my seatbelt mounting holes are going to line up. Might have to try and remove that and replace it with the proper crossmember so I can finally have middle row seatbelts. Nothing is ever easy with these trucks.....
