We recommend replacing your 1979-84 Mustang's steering rack bushings with Prothane urethane bushings when installing a new rack and pinion on your Mustang. Urethane does not flex like rubber for long lasting ride.
Polyurethane bushings are firm enough to control movement and maintain alignment in steering rack components without the harshness or resonance associated with solid metal suspension bushings.
Lifted or lowered suspensions, increases in horsepower, plus-size wheels and tires can subject traditional rubber suspension bushings to forces beyond their limits. Control arms, strut arms, leaf springs, body mounts, motor mounts, transmission mounts, sway bars and shocks all control movement and maintain alignment but the rubber bushings they use are designed for more "middle of the road" use. Rubber also deteriorates over time, further reducing control. This contributes to premature component failure, a "spongy" ride and less than ideal performance handling. Urethane bushings can correct these conditions, and improve drivability in your Mustang or Ford Lightning.
Had a problem with an order/quality issue. I put up a review stating so, and was contacted by Mike Linley, who was soooo nice and sooo professional, I almost felt bad about my review !! I felt the review was necessary because of bad welds/paint. Mike explained that they had a particular issue with that supplier and they had changed suppliers because of it. I must have mistakenly got an old set. (upper/lower Control arms-Foxbody). Mike asked a few questions, and was Sending me an updated replacement set while we were on the phone.!!! This is what I wish all Vendors would do; no arguments, no blame, no B.S. !! This is why LateModel stands out as an upstanding company, and backs up their products with AWESOME Customer service.
