11/3/19: After installing the seat belts, I was concerned what could happen in an accident now that we the occupants were securely strapped to the cab and the seat was not. I was looking at the seat and how it was attached to the cab. There is four 5/16” bolts that attach the seat frame to the seat riser. One of mine was changed to a bolt with no identifiable marking, wasn’t re-welded in, necessitating the use of a second wrench to tighten it. Since I had to change out the bolt and weld it in, I decided to change all of them to 3/8” grade 5. I used a die grinder with a cut-off wheel to remove the spot welds. Installed new bolts, welded them in, then added bigger, thicker washers and lock washers to complete this upgrade. While I was working on the seat slides, I noticed that the brackets holding these bolts were only spot welded in. I added a few welds to strengthen that attachment. I’m sure that there is still some weak points, but with these mods, I have eliminated the obvious ones.
