TFI on CJ7 install question

I am about to install the TFI ignition upgrade on my '84 CJ7 (258) and have a question about the coil (GP Sorenson 407S) mounting. I fabricated a mount from angle iron and intend to mount it to the fender well or firewall. Question, is there an issue with the metal bracket relative to grounding? Since the ignition coil mounting holes are metal and a part of the mechanism, do I need plastic or rubber washers to keep the module off the metal mounting frame? I just do not want to short or ground out the system.

Any help appreciated greatly.

Re: TFI on CJ7 install question

I've got my TFI coil mounted to the stock location on the side of the head. I cut out a bracket on the laser and formed it on the brake (jeez I'm gonna' miss working there!). So grounding the coil chassis is fine. Mine has worked for about 8 months now.

Re: TFI on CJ7 install question

Grounding the frame of the E-core coil is a really good idea.
Mounting it to the engine block is a better choice, but you should have no problems with mounting it to the fender.
