Thanks for the help guys!!!!!


but are you saying the crank flange is a different bolt pattern???
so what would I have to do get a later 225 flywheel and new clutch pressure plate??? if I cant find an adapter

How can I tell the model year of my 170????

The bolt pattern on the cranks are the same. What changed was the diameter of the centering register on the end of the crank. It got larger in '68. You may not need a different flywheel if you have a '68 up 170, and you won't need a new clutch unless the one you have is shot. If needed, a later flywheel would solve the problem and probably be cheaper than an adapter ring. Sorry, my bad.

Count the number of freeze plugs under the intake. '67 and older had 3. '68 up had 5.
