My dad called not to long ago telling me that the rearend is now installed and the disc brakes now work. Remember, the rearend is out of a 94 cop car and it went in perfectly like nothing changed from a 85 to an 94 caprice classic. There was some hangup with the bolt pattern on the rotors but that can be fixed by replacing the front assembly. The driveshaft was a little to long after the installation so they (Dad and Mark) shorten the drive shaft by a little and weld it up. It is not ready for racing until a new driveshaft is installed but it is ready for the transmission. Slowly but surely they are making progress on the car. I wish I was there to help in all of this work but we have remodeling going on which keeps me home when my family goes up to see family.
