M 3500 extended meter bridge instellation

Hello
Need help. Back in the day I dropped the big coin on a brand new m3500 32 ch. and a msr 16. I could not afford all the bells and whistles so I did not get the stand or the meter bridge. Well I just bought a second m 3500 ( yes Im a glutton for punishment) that has both those options I could not afford then. I want to remove the meter bridge from the new one I just bought and then re-install the meter bridge on my original m 3500 but don't have any literature on it and wondered if there was a resource or someone that could give me some pointers on the install. I dont want to screw something up and end up with to m3500s and no meters at all. Thanks in advance. M
