Mace you're a good sport.
I've been trying to get a hold of Mudraks for the past three weeks with no success
so I decided to call Jerry Nichols with colorado offroad express and he picked up the phone on the second ring. After 5 minutes of business and 20 minutes of chatting I got his info to pay for the 203 to splitcase doubler using paypal. I got my confirmation email saying the adapter was in stock and that he was just waiting for the tracking number. I'm happy I found his number on this board and if anyone needs it again here it is:
Jerry Nichols 719-576-0616 for the 203 to splitcase adapter
I was happy with the service. He also told me to watch out for the splitcase rebuild kits (since I asked) that replace the intermediate shaft. There have been kits with soft shafts. He said to test it with a file on the corner, it should dance on the metal. If it bites/files into it the shaft is not hardened enough and to send it back. He said these soft shafts are wearing groves in them in 1500 miles. So I thought I'd pass on the warning.
