Where could I find a good place for truck parts and accessories for a 1976 mack R600

It has a a handle that slides not one that pulls out.

It has a handle that you slide. Not a pull out one

It is on level ground. The king pin is against the fifth wheel plate. And it is what ever fifth wheel that was put on from factory in 76.

I have a ‘76 R600 the trailer has been hooked up for a couple of years just because we never used the truck. I’ve been getting it back running to haul a dozer. when i went to unlock the fifth wheel it seemed to be locked up. Im guessed do to the old grease that is packed in there. I need to know ways to clean the old grease out to get the fifth wheel freed up.
