Assuming you're asking about the M101 CDN...
I don't have any CAD files. There is quite a bit of part drawings and dimensional info on the M101 in the files of its Yahoo group:
http://autos.groups.yahoo.com/group/M101CDN/files/
You need to be a member to view the files, IIRC, but just hit the site with a membership request and you should be in. There may also be some older posts or members who could help.
