Has anyone used dennis carpenter cab mounts. I was looking in their catalog, and they have a drawing of their replacement cab mounts. Their people say their mounts are as close to orginals without having the factory stampings. but they dont seem to have an actual picture of thier parts...

 

They are excellent! I put in a pair, the only thing was the right side has a hole just like the e brake cable hole on the left side. All I did was plug it. The fit was good and the steel was much thicker than other mounts I've seen. I drilled out all the spot welds in the old ones, I went all the way through the cab floor as well. Then after cleaning it, I put the new cab mount in place and then used the holes in the floor board to weld the new mount in from inside the cab. Much easier this way. Don't drill your mount bolt holes until the cab is dropped down on the new mounts(bushing in place also) do that from the bottom.
It's not that hard to do, use a wire feed welder for best results.
