Rather than make new brackets when upgrading to 2854Rs I just drilled out the spot welds holding in stock actuators in and tapped some new holes on the back of the compressor housing. Had to cut the shaft down quite a bit on the drivers side but still had plenty of room for adjustment. Set them for 12 psi and they hold the 20 I've had the car up to on occasion no problem. Setting them up is pretty easy, built a little rig like this one:
I went with Forge because they have a piston setup rather than a diaphragm, they can be rebuilt/have the spring swapped and that's what Kuah told me to buy. Not necessarily in that order.
Not with those but I got some Forge adjustables -
