My next step is replacing my cab mounts. All four are pretty rusty, but so far the undercab rust is limited to the mounts. What's the best way to repair them? I'm assuming that the old ones need to be cut out and new ones welded in. Other options? Anything I should know?

Are you talking about the angled sheetmetal pieces on the cab or the brackets on the frame? If your talking about the brackets on the frame just weld some reinforcement like Zoomy said above. If it's actually the cab structure than those will need replaced. They do make ones that slip over the existing mounts but personally I wouldn't go that route. I'd go ahead and get the replacements and remove the old one (they are spot welded in) and weld in the new. It can be done with the cab on the truck.

The fronts will be easier then the rears, to do the front ones you have to drill out the spot welds which isnt as easy as it sounds. For the rear you have to cut and weld in new metal.

Sorry if I was unclear. I'm talking about the metal supports under the cab. They are rusty, which has allowed the cab to sink down about an inch. I guess there's a special bit for drilling out spot welds?

There is a special bit but you can get away with a regular one, I drilled out hundreds that way, I would have bought one but I never came across a place that sold them.

I just checked the Eastwood site - they have a couple of options. I guess I'm just worried about going through too much sheet metal, but that could happen with any kind of bit.

You usually end up having to drill half way through the second sheet anyways. Its nothing a welder can't fix. Sometimes the spot welds are not shaped round and you have to pry the metal apart, thats where the whole process gets frustrating.
