Mitsubishi Transfer Case to Tera Low231 NP231 ...

Update: March 27, 2008 I finally got the 4340 steel ordered from McMaster-Carr. Unfortunately, it's not heat treated. McMaster-Carr states it's Rockwell 20 and the shaft will need to be 38-42 Rockwell. Fortunately, there is a place up the street that does heat treating for a reasonable price. I finally gave up trying to get 4340 HT after about two dozen fruitless phone calls to every steel outlet and manufacture I could find. The adapter is coming along well and I managed to get started on the doubler case last weekend. I sniped the end of the t-case off and I've almost got the block off plate fitted. I'm sure that will be done and ready for welding by next Monday.

I have sent off just about all the CAD diagrams. I've already sent the CAD drawings off for the Tera Low231 shift cable bracket and transfer case support and got the pieces back. I'm still waiting for the t-case shift levers, and the bulkhead shifter cable bracket and a lengthened version of the Tera Low231 shifter pivot. I started to do some mock-ups and realized the original pivot will be a little too short once the shifter is mounted on the tunnel. Also, lengthening the pivot will shorten the throw on the shift lever a little which isn't shuch a bad thing. I've added some more pictures below of the 3/4 finished doubler, unfinished transfer case support and Low231 shift cable bracket. There's also some pictures of the inside of the doubler.
