Bellhousing dimensional drawing

So, i need a dimensional drawing for a gm 60 degree v6. Im trying to figure out if i can adapt it to a 1.8 miata trans. Then, make an adapter plate....

Also, anyone know what torque rating the stock nb miata 5 speed can handle?

Alternatively, learn me making accurate drawings of existing parts....

this engine is a common Fiero swap and I mean All Models of 60 deg. GM engines so check out Pennocks Fiero Forum.    some one there may have it handy or  look through previous posts.  

It's called the "metric" pattern. 

This is from the transmission side.

I love this place.

I fo und the metric drawings before posting, but wasn't sure if it was what i needed.
