The little metal standoffs can be robbed from the
mobile donor heatsink,they knock out nicely from the bottom with a drift. I have
hand redrilled the heatsinks,its a thankless,tedious job. 73,Lee

The only two that interchange I know of are the late 110 w VHF
75/100 w UHF. The early 110 w vhf that uses 4 transistors in the final
and the low band may interchange. I have both and I'll look.
Not only do you have to drill tap all the holes. You have to
rob the little metal stand offs from someplace, to hold down the circuit
board. I've done it on a drill press but a Bridgeport would be easer
more precise.

Actually it doesn't, most of the heat sinks are band
specific unless youwant to drill and tap about 20 some 6-32 and 14 4-40
holes in thealuminum to hold components down - I did it and it is a very
tediousproject.-- 73...Clark Beckman
