Here is an email he sent me about some other heating elements he had found. Some of it looks to be a cut and paste from the retailors website so you might be able to google the description:

The oven Im working on,,, what do you think about this as the new updated heating element? Only thing is,, I think it needs a temp limit switch,, Im trying to find a 325F limit switch that will fit into unit,,,

They're designed for use with metal containers. Thickness is 0.045"-0.08". All units are single phase and operate on 115 VAC, 60 Hz. They have 12" long wire leads . UL recognized and CSA certified.
Plain-Backing Blankets— Can be attached with a silicone rubber adhesive. Maximum operating temperature is 450° F. Can be exposed to temperatures from -170° to +400° F.
10 watts/sq. in. (for rapid warm-up and higher temperatures)
and this was in another email he had sent about the temp regulator:
"thermodisc is the temp sensor I installed to cut the coil off at 335F,,,, the coil was rated at 400F and will just keep going,,"
he also mentions that you might as well clean up and repaint the top black part of the oven while you have it apart. He used a flat flat black oven paint rated at 1200 F.
Lastly here is the picture of the coil he had settled on and mentioned above.
