One word answers leave much to be desired. Can you elaborate on the differences and whether or not the differences are even significant? So what is the difference, pressure, gears??
Personally, I doubt that they can't be interchanged. Currently, I own a 68, 88, and 95 vert top motor. I can't see that they wouldn't interchange. What am I missing?
A little more info would be great, I thought I read that someone was using an sn95 top motor for a 60's vert.
So if someone has the particular's as to why?
