I am, as usual, confused! I will be dropping the cab on the frame in a few weeks so I began to look around for cab mounts. I don't seem to be able to find what I need for the rear of the cab. All the vendors I have visited show a simple set of bolts like my from cab mounts. I don't see my rear mounts. see picture http://good-times.webshots.com/photo/2292589300099708909JNfYub
Is that because only 3600s (3/4 tons) use these and like many other parts for the 3600 and up they don't carry because of little demand?
OR, does someone know where I can order these mounts?
