Did you check with Cobra Transmissions? I did a full t-case rebuild last year and bought everything from them as a kit. I also bought a new front output shaft from them as well.

He did say parts were getting scarce though, so he may be out of stock by now too.

As far as the ATC500, Im subscribed! Would like to see it done.
