Anyone have a CAD file or detailed drawing of the face of the FD gearbox where it bolts to the bell housing?

 

I have seen similar requests come up before for FD gearbox bell housing patterns, and detailed CAD files are quite rare in public sources. Most people usually end up measuring from a clean transmission face or referencing factory workshop manuals. If you find a reliable drawing, it would definitely help the community a lot.

 

its also every rotary engine from 1974-2012, so it doesn't need to be an FD

 

that’s what I’ll probably end up doing, fortunately I have a CNC and good CAD software so if I get it I’ll post it here

 

Mazda 13b Bellhousing to Transmission Bolt Pattern - this is what I ended up with and it's what I'll use to make my adapter. Would recommend anyone wanting to use this to check it first.
