I have a high comp. glow plug but there’s an issue with it, the spring has been destroyed!
So I was wondering if there was any way to replace that, or if the plug is trash now. Thanks!

The coil is not replaceable therefore you need to purchase a new one.

While the plug lost its glow, you may want to consider using it to create a turbo-plug adapter from it. I haven't tried it yet, but expect to once I blow a few plugs.
There is a thread over on RCG showing how to do it using a small drill press, cheap phillips-bit. And a rap. Apparently the phillips-bit has the right angle to allow the turbo-plug to seal.

Right now I have about four or five heads waiting for the treatment.

Please explain destroyed. Usually when a glow plug goes bad, its bad. But occasionally the filament is just distorted and shorted to the side of the filament recess, and there is a possibility that it can be re-centered using a pin. I've used a t-pin in the past to re-center the filament and get a glow again.

The top half of the filament is simply gone, so I don’t think that could work.

Just go to Cox international, they will hook you up with a brand new glow head and you'll be off and running!!! Don't stress, have fun, Mark

You will lose some power with the conversion plug unless it uses the turbo plugs, or Nelson style plugs. The high compression Tee Dee Cox ones are still available I think, and are good. I would not get the low compression ones myself. They are already pretty marginal on power. One thing that made Cox so popular was the fact that they used a dedicated head rather than a regular plug.
