I bought a running 1960 motor for a spare that was in a 1951 3100 6 volt system that had the 2 condensers. The other thing I noticed that the front motor plate where that is located behind the timing gear set had the holes in the bottom and it was mounted where the original 1951 motor was mounted on the cross member. I am not sure how the 60-62 mounted I do know they do not have the bosses on the front of the motor to attach the bird leg mounts like on my 1956 3100. So if it was me I'd drill or if I was going to do any motor work I would change out the front motor plate. I installed the 1960 front motor on my 1956 block so if I ever pulled the motor and decided to put it in another ride I could use what ever means to mount it. just my .02
