I thnk Phil wanted to put his manual AAR in his automatic T3.
No, no  place for a manual AAR in the T4 engine, I will find a way to do
what I want with the electric one.

:You make a very good point and ask a reasonable question, but Keith's 
asking about a Type 4 engine. Is there a place for the non-electric AAR in a

Type 4 case?
