Hey, Could this work on our dashes as well? (pics. kinda big, sorry)

Yes, and actually it will work on most if not all mopars late 60's up through early 80's, any that use the same voltage limiter. The instructions are all there in the article. I still have that magazine issue. Small note/word of warning, you may want to consider pulling the post and offering up an e-mail addy to any who want the info and share it in private pm's or else everyone who wants it best copy it now quick while it is up, you are in serious violation of copyright laws and the magazine companies can be real A$$holes about stuff like that, no matter how many people your helping out and you could also get this web site in a lot of trouble and cause it to not be here anymore, that would be very very bad. Just food for thought.
