Here are some pictures.
These wont help with anything besides a 949 twin disc, but should help anyone else planning.
Waiting on some measurements from sean for the crank, but we might end up having to take a bit off of the end of the input shaft.
And maybe some custom discs, don't know yet.

What is the general consensus on input shaft spline engagement. With the twin disc and the t5 input shaft I would be missing about .12" out of like .75". But only on one disc.

Engaged. I remeasured. It's like .04 out of .35 or something. I still haven't drawn it all up.
worst case is I strip a disc or input shaft. Still have a second to limp home on.

Built a little fixture to align the tailshaft housing. This aligns the shift rod hole on the mill and lets me drill a hole for the extension on the back of the T5 perfectly.

Just found a t5 flange drawing on an alfa site.
Another T5 Conversion Thread - Alfa Romeo Bulletin Board & Forums
And here is my version with the holes for the alfa bellhousing removed.
Printed one out. Going to check it on the trans tonight.
Going to rough cut a miata bellhousing to make sure I don't need to add any material anywhere and then get this waterjetted.
