I also used Superbrightled.com for all my LED purchases this far on my 71' e body. I like that theyr un cooler, and don't tax the wiring or connections as bad. I'm not going LED for the headlights or front parking lights (clear lenses so you can see the bulbs), but everything else is getting them.
I haven't done headlights yet either. I can't find one that is plug and play and doesn't look funny. I have a spear covering the tip of the front marker light in the Monte. It has a clear lens and amber bulb. Looks good and can only notice it's LED if you get up close enough and look at an angle. If it was an open lens to see the bulb, I would go with a regular bulb.
