New car, new problems; 76 Duster 318

Ya, I have a feeling I'm gonna have to tear the dash apart... Lets just hope she comes apart (fairly) easily....

Also, was planning a tune-up sans oil change (can wait, since she's parked until temp plates come); everything from the coil to the plug. Also, will play with distro timing and see if that does anything better/worse. Also also, will play with carb settings.

As for the U-joints, is there any way to spruce these up for now? Maybe some oil or grease? Don't really have the dollars for a new driveshaft at the moment; registration, insurance, and a cool old car sorta ate up all my spending money this month...

Anyone have any recommendation on spark plug brands/types? I know the rule of thumb is NGK in an import engine (I run NGK Iridiums in my Isuzu P'up, and she LOVES it), but what are the best for a Chrysler? Looking for something hot so I won't have to replace them later, but then again plugs are plugs for the most part... Still, will need something that carries a billion kV, since I plan to put a hotter ignition system in eventually...

GTX: That's the plan... I want to get her reliable, then work on de-uglifying her and getting her a proper body job (80 scratches, sagging paint, rust, wipe marks, peeling clear, etc. all over)...

Also, since my state has no emissions testing etc, I was thinking of straight pipes off headers... I won't need the "smog pump" (air pump) anymore. Is there an easy way to cut this piece of crap off? I also have a sneaking suspicion that this could be part of the problem as well (exhaust sounds plugged and tailpipe is insanely sooty (no smoke or stank, though it could be because it's a 37 year-old exhaust pipe).... This part wouldn't happen to be the big ugly chunk of black plastic thing in front of the carb, would it?

U-joints...I doubt it. usually u-joints show up during steady cruise or while decelerating. Sounds more like a pinion gear bearing to me.
I thought the same thing, but will still check the U-joints... After all, it starts under acceleration but then goes away completely when you let off the gas. If it was running gear, I'd speculate on it happening as a constant and increasing/decreasing relative to speed...


So, I get to spend my 4-day weekend tearing my Mopar apart! :D

Thanks,
