Go to the local parts house and get your bushings, you wont have to pay freight that way. I just picked up a set of RA bushings for my 78 a couple of days ago. They were like 19 bucks for both sides and high quality. Most engine, chassis and electrical parts are still available for these trucks (Where do you think LMC and NPD get them?) Stay away from the chain autoparts places (Autozone etc.) Go to the good old locally owned "old school" places and you'll be amazed at what they can still get for a 40+ year old truck...............
