[V8] IC cold solder joints

[Ron Wainwright]

@ least you'll be an expert IC remover/installer ;-)

 & thank you for the kind words. In your case I thought that the problem lied in the cluster & not the Blk box.... but just needed some background on what you have tried, & when it started to happen. But,
I'm not in the biz of selling or giveing parts away that someone doesn't need.
 I try to help out as much as I can! I LOVE these cars!!!!!!
