Used to be made of phoenlic, I'm not sure about what they are made of today, the thin plastic ones will heat up and warp over time and the blade will become loose in it's mount.

i did some searching today for a new distributor on summitracing.com and I did't realize how much of a selection there really is. I saved two that i posted on here to get some opinions on which would be better. Also for instance if i choose a Mallory Dist. should i also go with Mallory wires to match instead of mix and matching name brands?
