I got the Newport's as well through Bowtie Bits. No real world service yet but install worked as described, a quick test shows everything in working order. I added an aftermarket switch with delay and washer pump feature, looks just like the one it came with, plan to put a generic period correct knob on it for further "originality".

If you return their drill jigs you get a t-shirt - better than a poke in the eye.

I'd also suggest mounting using rubber washers to minimize operating noise.
