<strong>Yahoo Message Number: 65382</strong>Country Coach Owners Association You are correct, I meant to say the shaft is 5/16" in diameter. Actually, if I could find an assembly that included a motor and squirrel cages on a base that is 16 1/4 to 16 1/2" long and 7 1/4 to 7 1/2" wide, the size of the shaft would not matter.<br/><br/>Gene<br/><br/>2000 Allure
