51 F-1 Frame to Cab Mounts
I am a month or two away from installing the cab on my 51 F-1 for, hopefully, the last time. Before I do, I have a question that you all may have an answer too.
The four forward cab mounts on the frame have bolt holes that look worn and wollowed out.
They look as though the body mount bolts had been loose for many of the trucks 60 + years and have worn the holes larger than needed.
Are they supposed to look that way or do I need to weld them up and redrill the mount holes.
I know that the rubber mounts will isolate the body from the frame, but will the wallowed out holes allow the cab to shift, causing front sheet metal and hood alignment problems.
Let me know what you all think.
Thanks
Dan

Look pretty normal to me from what I remember of mine. Amazingly I have no direct pics of the mounts from either of my trucks, and I have truck #1's chassis covered up and cannot easily get a picture.

Any of the reproduction parts companies will sell a cab mounting hardware kit that has the bolts.

If you have one to measure (Ford typically used fine thread bolts and nuts), you can get them at any good hardware/fastener supplier like McMaster-Carr. Locally Home Depot, Lowes has some sizes in the long thin drawers of specialty hardware. My local Ace hardware carries a fair selection. I have replaced most of the body bolts and nuts with stainless button head cap screws and nylon lock nuts.

I dont expect front frame flex as stock with my jag crossmember welded in, so I have regular hardware 1/2" bolts at the front 4 body bolts and regular carriage bolts on the radiator support with no springs.

Aha! I learned something else that is different between the F1 and F100s. Now I understand why all the F1 have wallowed out bolt holes. Once the rubber pads started to deteriorate the shoulder bolts beat out the holes. Which one is supposed to go where, and head up or down?

Well it looks as though we have a consensus rather than an answer. So far everyone seems to have frame mount pads that look somewhat the same. So, I am going to put my cab back on the frame and rely on the new rubber isolators and bolts to hold everything together. Someone else will see how the mounts last for the next 64 years. I'll just drive it until they take my driver's license away.
Thanks to all that replied.
I appreciate the help as always

I said wallowed out holes only because that's the way they look, not because they are, Since most all look the same it very well could be the way they came from the factory, possibly to allow movement, or ease of assembly. Unless someone has/could examine a NOS frame to verify one way or the other, or careful examination when assembling with the proper bolts and pads might give a clue. My thought are much like yours, that the cab is likely to move around a whole lot less on today's much smoother roads, softer/modified suspensions, easier life to create much concern one way or the other.
