Rail Upgrade Help Needed

[Towersonline]

I am converting a PRT 48x48 to 48x96. I received the new rails from ShopBot Friday and all that was in the box were rails no hardware or instructions. The new rails are the aluminum PRS style, (ShopBot no longer supplies the older style PRT rails). Has any one done the conversion? If so would you be willing to send a few photos to the e-mail address in my profile? Some questions come to mind. It appears that the C-channel needs to be re-drilled to accommodate the new rails. Are spacers used under the rails? How are the prox switch targets mounted? Any suggestions are welcomed, I just hate reinventing the wheel.

Thanks, Bill Thorpe
