2.3/T5 block schematic or blueprint?

[willys2point3]

This is a longshot and a little off topic, but I'm curious if anyone may have or know where to find a schematic of the rear of a 2.3 block with the T-5 bellhousing mounting pattern? Something precise enough that could be used to reproduce a bellhousing mounting/adapter plate?

I've not seen that info anywhere.
