The composite firewall is only about 7/16 inch thick (1/4 inch plywood covered with fiberglasss, two compressible layers of 1/8 in fiberfrax and the thin stainless steel firestop). Probably a 2.5 inch long 5/16x18 threaded rod (about the thickness of #4 wire) with the center 1/2 inch unthreaded would do the job. Today I talked to a person familar with boats and he said he has seen similar brass terminal posts. I think brass or a brass alloy might work, but I want to consult a conductivity chart first. Also, whatever is used must withstand vibration and a torque load of GOODNTITE. Tomorrow I will try to check with "boat people". (Yes, we have them in the Midwest) Scott Krueger N92EX
