These mounts were then bolted to the frame, again using the grade-5 hardware supplied with the kit. | 
In the stock application, Corvettes use a torque arm to control the pinion and prevent it from trying to rotate under acceleration. The torque arm is replaced by a crossmember in the truck installations. This bracket bolts to the differential where the torque arm once was located. Again, these are metric bolts-make sure you get these items with your rearend assembly when the salvage yard removes the original torque arm. | 
Using this precise digital level, Don made sure that the pinion angle was set to the preferred 2 to 3 degrees. He will match the output shaft angle of the transmission when he mounts the motor and trans. If your engine and transmission are already installed in the chassis, you will want to match their angle. This is necessary to eliminate possible driveshaft vibrations. |
These combination- gusset/mounting plates were slipped into the frame. They will mount the crossmember that holds the front of the differential. | 
When we were satisfied with the placement of the plates, Don welded them to the frame. These do come drilled for bolts, but it was decided that the holes were in a rather tough place to drill. Therefore, welding would make for a stronger mount. Out came the MIG welder. | 
The crossmember was bolted to the differential mount that was previously installed. Then it was checked for level from side to side. |
Once he was satisfied that the crossmember was perfectly level, Peter used a transfer punch to mark where the holes would be drilled. | 
Using the center punched holes as his guide, Peter brought out the Rota Broach once again and made quick work of the four 3/8-inch holes. | 
The crossmember was then bolted to the gussets. The install was getting very close to being finished. All that remained to be installed were the shock mounts. |
