I'll drop it after this post - both of you said "you cannot convert a non-lockup to a lockup".

That is false. And if you do not use the early model valve body with the lockup module - NO grinding is needed. And yes - just a little grinding, not near the amount needed to install a Hemi in an Isetta. People come to this site hopefully to get good useful info - your two posts were glaringly wrong when you both said "you cannot convert a non-lockup to a lockup".
