I have a 86 GT. The smog pump pulley has a lot of movement. The original pump has 170,000 miles so I am sure it needs help. I do not have emissions testing where I live. I have read about smog pump eliminator pulley and bracket. After the pump is removed what else is required to block off the exhaust and to keep the motor running good. The car has all other smog devises in place and operating. NAPA has rebuilt pumps for $235 less my military discount.
