Help! L760 Rl70 cables and trunnion mounts.

Hello,

My friend recently upgraded his systems in his powerboat and gave me a great deal on his old equipment. I have a sailboat, so mounting the SL72 Plus on the mast requires longer cables. I have exhausted all of my internet searchings on cables and trunnion mounts.

I have a center cockpit 42 foot Mapleleaf, so I need some good distance for cables. I already have a GPS unit, but I do not have radar. My goal is to either hook both units up and have a backup GPS, or if that's too difficult, just run the SL72 Scanner and the Rl70 display. So I was wondering if anyone could help;

1- I have the L760 and RL70 screens with the SL72 Plus scanner. Are there current cables and extensions that fit these units from newer applications? I can't find anything used on eBay etc. If so what are these cables, what size and for which unit?

2- The L760 and RL70 were flush mounted in my friend's boat, so I need trunnion mounts for them in my boat. I can't find them anywhere. Are there again current applications that would fit? or a generic brand of trunnion that would fit?

Thank you in advance! Cheers
