Look at W6KGBs article on moving 450-470 Mastr IIs to 420-450. It's on the GE Mastr II page at repeater-builder.
You could use a Mastr II UHF mobile with the receiver, exciter and IPA converted to 420, then use the receiver in an aux receiver chassis at the voter site. You wouldn't need to convert the PA, the IPA (driver) and a beam would be enough for a point-to-point link. Bob Meister WA1MIK did an article on converting the multiplier chains so that the UHF Micor receivers could hear down as low as 435 MHz (where the front ends run out of tuning range).
