The DRB's utilize the 85 -87 C-4 Corvette suspension pieces. It's rare, but sooner or later you will have to rebuild the ball joints and bushings.
I was able to remove the buhsings with a mini press, but was not able to get the ball joints out. So I took the pieces to a local performance shop specializing in corvettes.They were able to pop the old ones out with no trouble. We were planning on using the AC Delco units, but found they didn't fit. We tried two or three others to no avail. Most were 2/100" off in diameter. I consulted with a vette restoration shop in Pittsburg and they used Moog and another brand. Their suggestion was to heatup the arm and "pop" the aftermarket ones in. On further inspection of the arms, the outside edges of the arm is rather thin at best and my shop had seen some crack, making the arm a door stop. So we went with the GM parts which went right in (at $30 more for each ball joint). Most chevy shops don't like to work on C-4s as they are considered old by their standards. They had rather work on the C-5s. I was surprised at the variance in the aftermarket parts. My suspension parts must have been exposed to the elements for some time as the rubber parts were dried out and cracked and were useless. If you have a press and want to do it yourself, watchout for variances in the aftermarket parts.
