Over the last few months, I've completed work on my B2B (ship 430) including an Infinity Grip, with active trim, using both new and old systems, new cable for rotor system and fuel sending units and a 2 in 1 gauge. They all work great, it was fairly costly, but effective and can be done in a couple of days by your A&P.
If interested let me know and I can provide pics and installation stories.
