As to replacing your rear cab mounts, that shouldn't be difficult. I'd do it by removing the three body mount bolts on one side and jacking the cab off the frame. Shouldn't require more than an inch after the weight is off the mounts. Then lower the cab, replace, and tighten the bolts back.
Repeat for the other side. An hour job by my estimates.
