Installation The first step is to locate and drill the mounting holes for the front shaft. With the track and driveshaft out of the way, it's easiest to do this from inside the tunnel. Keep in mind that you need to subtract a quarter inch from the given height measurement since the distances usually are stated to the top of the tunnel. Butch is a carpenter by trade, so laying out the drill points came naturally to him.
If this is your first time, take some extra time and double-check your layout. Remember, measure twice and drill once!
Production tunnels have mounting holes die stamped, and these are accurate (at least in the horizontal direction) and can be used to great advantage to double-check the layout from side to side. When the front mounting holes are drilled in the tunnel, mount the cross shafts and then sight it in against the driveshaft to make sure they're parallel.
You may have to elongate one hole to make it parallel before riveting the reinforcement plate in place. This small adjustment will be covered by the plate. The same procedure goes for the rear bracket. Sometimes one mounting hole on the rear bracket ends up right at the bend of the running board, and you may want to move it down slightly to clear the bolt. This can be taken up with adjustments in the suspension, but it seems to work better if you slightly move it down to make sure you have adequate tunnel clearance.
With the track and driveshaft back in place and the suspension installed, the rear wheel shaft ended up in the middle of the adjusting slot, and Butch declared it a "good install."
In addition to the track, we ended up using the new Wahl Brothers skis up front with the rubber coated billet wheels, and these are a lot stronger than the earlier plastic wheels. The skis installed quickly without any problems.
