vibration problem

.................OK guys.........i fixed a 74 duster awhile ago.........as i've did and so have others with aftermarket wheels that required the weights come off the rear drums so they fit flat to the hub and not have a problem with wobbling..........the guy tried alot of things, nothing helped it.........put on a new set of drums with the weights on them, 1 problem solved as now he needs different wheels as they wont sit flat with the weights on.......not a bit of vibration with the rallye wheels.......he's happy the vibe is fixed, but totally pissed at the tire shop that sold him rims and tires[over $1000.00] worth.....they said the wheels were wobbling, so they removed the weights and threw them away.....ofcourse he was chasing this vibe 4 a few years, so they wont do anything 4 him......it will cost him $100.00 per each rear wheel 2 have them milled out to clear the weights................kim...............
