Bud, To bad those wing tips were just maybe an 1/8 longer then it would be fine.

I have been talking with Keleo on his exhaust for the OS 160. Apparently with some pictures of the engine installation mainly head on and at 90 degrees to the firewall he can lay a protractor on it and setup his jig. I told him about my concern of the right cylinder exhaust hitting the cowl and he is going to see what he can do about that clearance. He is busy now so Im waiting for a time table on when he can get to mine
