You can try Ebay...no guarantees, but it's a place to start. The 379, 401 and 478 were also the engines of that particular time, but I don't know about interchangeability of the seals. Good luck...

Have you looked under the rear seats?

Fun a fuel flow test on the fuel system. You may have a restriction in the lines of filter. Also make sure that nothing is blocking the accelerator peddle from opening all the way. Use a scanner and check voltage the throttle body is getting from the sender.

You do not need to "flush" the AC system, but you will need to put a vacuum pump on it to evacuate all of the air before charging with new refrigerant and the recommended amount of oil charge. It appears that the refrigerant is R-134a and the system takes 48 ounces for a front and rear system or 29 ounces for a front only system. The specified oil is PAG46 and you will need 8.5 ounces for a front and rear system and 7.5 ounces for a front only system. The first link below is the specification page and the second is a video showing how to charge the system. The big parts chain stores will loan or rent the necessary tools and will be happy to sell you the refrigerant and lubricant.

Check the exhaust for leaks by briefly holding your hand or similar over the tailpipe when the engine is idling - if there is a leak get it fixed, if there isn't consider extending the tailpipe length.

It is also worth checking the door and tailgate seals and adjustment...

Hi, Any other issues w/the truck? Does the speedometer work ALL the time? Some of these use engine vacuum to control the Cruise. Check under the hood -around the engine - and verify the vacuum lines are all securely attached. BE CAREFUL - do this w/the engine off and ENSURE you note where all the hoses are connected. There may be a lot and easy to get them confused.
