Help..
Does anybody have a thunderbolt transistorized CD box that bolts to the exhaust riser for a 454 magnum. Mine is fried. I know many folks have converted to an aftermarket system and I'm hoping that someone might have a good used one or two that they would want to sell.
I would be very grateful.

We need to know which one you need. I mean which advance box you have or need. If you look at the numbers on the box you can cross it to a new number. That will help us find what you need. Good luck!

Anthony,
Thanks for your response. The number on my power pack is: 7J16A V8 - 24

I have a bunch of older units without the plug. They work well. Make sure whatever you do to insulate them from the elbow and also insure you are running cool enough. These things need to dissipate heat not absorb it. BBB
