I'd like to fabricate an assembly that mounts an SCG tuner and a whip on the rear or roof of my Honda Element, using the type of magnets used in multiple magnet antenna mounts. Does anyone know who sells the individual magnets *without* the antenna mount hardware and coax?

Well, you might say goodbye to your SGC auto-coupler if you decide to use magnets. This is why SGC uses a special window mount for the mobile coupler/antenna setup.

Mag mounts, no matter what you use, or how many, will dislodge if you have a crash and the more they weigh the more potential energy they'll have when they hit something or someone.

If you just can't help yourself, Lakewood Engineering does sell a tri-magnet mount and they might sell you the individual parts.

It should be noted too that in addition to several/lots of strong magnets a thick solid ferromagnetic metal mounting surface would be desireable, e.g. 1/4", 3/8" (or more) steel plate vs. thin sheet steel for max holding power. Of course it you are parked it is a whole differant ball game than moving.  All depends on the application.

You might web surf for magnets -- ferrites (thinner w/ large pole surfaces vs either alnicos (small poles, long form factor) or rare earths (very strong but very expensive, unless small volume is critical and they're worth the cost). Edmund Scientific might have large ferrite disks for reasonable money too.

The coupler is very light, and a friend made a similar mount with magnets found at a swap. His has been on three company cars over a few years so I'm not too worried about it dislodging.

Still, I may do a trailer hitch receiver mount.  Depends what I can find.

I buy Iron Horse or similar multiple-magnet mounts and cannibalize 'em.
