Well, I had some time today so I stripped the rear axle, premix tank and exhaust from the old 175 and started fitting the Pro Tec Suspension kit. You have to remove the axle adjuster, grind the nut down attached to the frame for the bolt that holds the axle adjuster and open the hole up to 7/16". The 7/16" drill bit is a little too big for my drill so I'm going to have to buy one of those bit with the stepped down shank tomorrow morning. I'm not cleaning it up too much as this is the trial fitting and once things are fit and finalized, then I will clean it up and reassemble it. I've got a couple pictures and some pics of the nos parts I've been collecting. The pitures of the frame are kind of dark since it's late and back in my garage. The first pictures is of the trike before removing anything for the suspension kit. The second picture is of the top shock mount bolted in place. The third picture shows the axle and adjuster and oil tank unbolted. The final picture is one of my Pro Tec suspension kits.
