I just got a trap door rest from a fellow AT'er here, and am having problems setting it up. Does anyone know of a pdf or anyone who can scan in the instructions to the rest and let me look at them. I have the mach 4 version. any help would be great, the website doesn't work, and I have done endless searches, only to come up with endless site's that want to sell me another rest, but I don't need another one, just want to know how to set up and adjust this one. Thanks.
