Does this mount from inside the cab or does the cab sit on top of this?? This is for the rear.

Cab sits on top of it. Bolts go in from the bottom.

Oh shoots!! I thought the bolt goes from the top. Thanks for mentioning that. Also thanks for telling me the cab sits on top.

So how far does the cab have to move up to replace these? Does it mean all sheetmetal has to be removed?

All I’ve done in the past is loosen all the bolts including the core support on one side, then shove a 4x4 or similar piece of lumber under the cab floor, and jack the whole side up a couple inches. Swap the mounts then bolt it up and move to the other side.

Thanks everyone for replying. This helps out alot. Hopefully the cab will be back soon from ther body shop. Frame and suspension is done. Wanna have the cab mounts ready so when the shop brings the cab to my house, we can just plop it onto the cab mounts.
