Couch mounts

Are couch mounts taller than sj mounts? I want to buy some for a new build, but I've never done this mod. Just want to make sure my couplers still line up. And I won't have any crazy alignment issues.
 
Couch mounts are a tiny bit taller. Usually its enough moving them towards the side of the ski before tightening the screws.. If that isn't enough you drill the hole in the bedplates a tiny bit bigger, and it will fit nicely.. Good upgrade running couch mounts instead of SJ mounts..
 
I hold the mounts in a gloved hand and using a high speed metal cutting saw with an abrasive blade, I lock the saw on and press the base of the mount against the side of the blade. I rotate the motor mount as I'm shaving the bottom off until I get to the right thickness. Might not be the safest but sure works well and have never had a failure. Takes less then a minute to do each one.
 
I always ran them in my superjet and had a set of rhaas mounts in my rickter when I built it. I decided to go with couch mounts in my rickter after half a season of riding. I ordered 4 brand new oem couch mounts. I had to mill a light 1/8" off the bottom and almost 3/16" off the bed plates to get them to align properly
