I skipped a step in the process. Once the cab floor & associated parts were installed, cab was set back on the frame. I wasn't concerned about the rear cab mount location, but the front mounting area had received a lot of work with potential for mis -alignment . Thankfully, all lined up well. I used the newer style polyurethane bushings. Since then I've read some are complaining they ride too harshly & help transmit noise. They're in there now, so I'll just keep the bolts tight & see what happens.
I have to admit, it felt good to have cab mounted on frame again. Felt like I'd finished phase one. Only 999 more phases to go LOL.
