transmission bellhousing bolt pattern CAD wanted

Good evening all, I am trying to put a little jap diesel on my AX15. I am looking for a CAD or engineering drawing for the bell housing bolt pattern where it bolts to the I6 block. I found some info from other sources, but they are all a bit different from what I am seeing on my bell housing.
Plus the bolt holes in my bell are a bit tapered. with the small ID under the bolt head, and about .030" larger at the face that bolts to the block

Any help would be appreciated

On ebay I've seen bellhousings for less than $50 shipped and you can trace it out for your self, then resell. Just a thought.

I have bell housings a plenty more than I need. I wanted the engineering / CAD drawings to show the measurements off center for all the bolt holes, and the bolt holes original diameter.
