CB-1 fuselage extension

[bwwillis]

I was corresponding with fellow in Fresno last week who had a CB-1 project for sale. He said the fuselage was extended 9 in. to allow for larger pilots and the Lyc O-320 engine. He had plans for this drawn by Kelly in 2003. Also he had the original plans for the shorter fus. I'm wondering what version the Hatz Assoc. sells. I was not the high bidder so some else gets the details on this one. My CB-1 plans show very little for the O-320 engine version and my Classic plans which uses the O-320 is a couple inches shorter than the CB-1. Someone please educate me on the versions of the fuselage.
