I have put you on the list, Allen.

I guess I will have to talk to the machinist about flexible tooling, and
fixtures. NC programs will have to be modified too.

I am also interested in a slide throttle for a 20b as an IO-540
replacement

Add me to the 20B list, too.
And I vote for red anodizing.

Doc,
I may have missed someone's reply to your question, but NO, the spacing
on the third rotor isn't the same.  I think it is 2", but I'll have to
measure and check.  There's a third main bearing in that side housing.

Thanks,
Mark

Mark my 20B is in the hangar. Can you measure the width of
the housing for me. I think I have it somewhere but a double
check won't hurt.
