I'm sure Mark(mrsaltwatertank) had someone do it for him in Austin. He's a self proclaimed anti DIY guy. It looked fairly simple though. You should PM Mel (New Wave), he could handle that for you, if he has any time.
I did something similar with my DIY led heatsink I got the idea from watching mrsaltwatertank . Measure the dimensions on the inside lip of your tank have a piece of plywood cut to that dimension then route out a hole with a lip on the water side of the plywood so the radion fits into the hole and rests on the lip. I did mine a little wierd I cut the hole small the first time and made it bigger in small increments till it fits. I didn't want to cut it big the first time and the trick is to sand and paint with a paint that's going to protect it really well. Then you can cut and add hinges for a feeding door..ect I hope this helps but just make sure you get the measurements are exact !!
