A good heatsink for the IRF510's is an aluminum enclosure.
Could just put a chunk of aluminum or copper between the IRF510's and the back panel of your enclose.
Or could mount the IRF510's to the bottom of the uBitx main board, bend them back 90 degrees,
and bolt the IRF510 tabs to the bottom of the chassis.??
Keep the IRF510 leads short, insulate them from the chassis and from each other.
Going for higher power?
Good luck, many ways this can fail if you push it.

Custom heat sinks can be made from 2 or 3 thicknesses of
aluminum folded to look like a conventional heat sink, or just
a large flat square of aluminum.? Tubular heat sinks can be made
so that the fan directs air through the heat sink itself.
