Randy - the whole core exchange idea just didn't hold water.
I've done a few conversions for people, though. It just requires you to pull all the items you want converted and shipping them to me. Being centrally located (KC area), shipping is fairly quick (about 3 days each way to either coast).
If you daily drive your car, this is basically impossible, but if you can go a week or so without, I can help you out.
The only thing that I won't touch are the earlier clusters (like mine in the picture). Their LCDs are just far too sensitive to be shipped. I've bought three clusters in an attempt to replace my damaged LCD. All were fine before being shipped to me (as verified by pictures before being shipped), but arrived with 1 or more damaged LCDs.
The good news is that those older style style clusters are easy for you to do as you can just purchase a kit and swap the bulbs. Everything else requires soldering.
