Need to use the old style because of the outlet, needs to be on the left side to work with my new 66 style Rad.....

Keep the original vibration damper for the 360 so it's balanced correctly... The mark will be 90° off...

Just put the engine at TDC and draw a new timing mark on the balancer where the old style timing marks will be at 0°/TDC....

Then you will have the proper radiator hose fit, proper balance, and then also be able to run the 66 style molded radiator hoses....
