Hi All
I'm currently installing a Tom Pryor Drum/Drum Reaction arm kit and having some issues that I believe are design related and looking for advise from members that have experiencing installing this kit themselves. Firstly I a bit disappointed that the kit was missing some of the installation tools and supplies that are indicated as being part of the kit. OK I was able to acquire what I needed but why? The Next problem is that the instructions illustrations do not match well the actual parts of the kit.
The trunion bearing on the rear of the torque box illustrations or instructions simply show a round plate but the actual plate has a flange. The instructions show to install the torque box plates on the trunion, But that would mean that the flange actually increases the space between the plates and they will not bolt up. If put the trunion after the box (With the Fl;ange on the outside then it seems to fit better so I'm not sure Im right but I hope so.
The real problem right now is that when I need to install the backing plate on the torsion box it WILL NOT seat. The lower two bolts of the lower spacer plates are too high on the torque box!!?? They interfere with the flange of the backing plate??!! They should neatly protrude into the indentation of the backing plate so there would be no problem. The bolts should be at least 1/2 inch or more lower on the torsion box ( The Box should be longer by that much too!!!)
In order to allow the nuts, Lock washers and bolts to fit I experimented with drilling large holes in the backing plates as a relief for the fasteners and it seems to work at the moment BUT Why do I have to re-engineer this thing?? I have photos in a personal photo album to more clearly describe my problem. its at:

If you have installed one of these kits, What did you do to accomplish this task without the re-engineering of the plate? Do you have any advise I need that I seem to be missing? There are another couple of issues that concern me and that is that it does not rotate and use the spindle as a means of centering the backing plate in the drum. Normally the backing plate is positioned centered on the spindle, It certainly seems to "Float" Way to much for my liking. I haven't been able to get it finished enough to actually see how it works but I'm Concerned.
All help will be appreciated.
