Swan changed to the 6JH8, probably for cost reasons.

That's true, but the Swan transceivers weren't using the 7360 as a
receiving mixer. They were using it as the balanced modulator in the
transmitter section, which is a very different job, and the 6JH8 was a
low-cost alternative.

The 6JH8 could probably be used (with mods) in a lot of SSB
transmitter projects from the hollowstate era, rather than the 7360.

I've tried both, and the 7360 wins by a long way - it
probably proves
that "you get what you pay for"! �The 7360 gave me
useful conversion gain,
a spectacularly high intercept, and as low a noise figure
as you could ever
wish for.

What circuit and values did you use, Bob? Voltages, balanced vs.
unbalanced, output and input circuits, etc.?
