55.2 cab mounts

[55cruiser]

I have a 55.2 short box step side, that i aquired, there is no rubber between front cab mount and front frame mounts. There is rubber on rear mounts. I think there should be rubber insulator on the front am I right? I have attached pics of front and rear mounts, can they be replaced by jacking up the cab, one side at a time. The hood is not a great fit it looks like the cab is slopping on a down ward angle. When I view cab mounts from suppliers they only seem to show 2 square ones and 2 round ones plus some shims and bolts. THANKS
