Got the motor mounted today. I also had to fill holes and re drill. My cowl mounting ring was broken also but like you said, it's no problem. Cowl not mounted yet as the dummy radial is curing. I also don't care for the hard foam wheels bit I have a pair of Du Bro 5" that I think will work fine. I am doing the Canadian Forces plane also and graphics are ordered. Also ordered landing lights and new spinner for 3 blade prop.
