That's where I got mine.

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 you
want to drill and tap about 20 some 6-32 and 14 4-40 holes in the
aluminum to hold components down - I did it and it is a very tedious
project.
