cab mounts for 77
 

I have checked around and looks like you can't get new cab mounts for a 77. Will the 81-87 mounts match up to my frame, or will I have to drill new holes?

Hmmm ... I just checked the LMC catalog and they're still showing cab mounts available for 73-80 in both OE style rubber and performance polyurethane.

I don't think the cab mount locations changed so you probably wouldn't have to drill any new holes to use 81-87 style mounts. Height might be a concern though. For example, 73-80 3/4 and 1 tons as well as 1/2 ton 4x4's used taller rear cab mounts than 73-80 1/2 ton 2wd or 81-87's. So spacers would be necessary to make 81-87 mounts fit those applications.

the cab mounts are readilly available from several vendors . You must use the cab mounts compatible to your frame or the cab will not sit right

I am sorry, I spoke wrong before. I meant the bracket-body mounts. (19) In the lmc cat on page 35 in the new catalog. They do not have these for 73-80. Will they be the same? I have the correct cab to frame mounting kit.
