This is an old thread, but I have an interest in it as well.  I recently rebuilt a 70 Surpass and it uses the 45960200 valve springs also.  I do have some of the 0210 type for the Surpass II, and I see the O.S. rep above says they fit, but this seems like a mistake.  The new springs not only are wider, but are shorter.  As they are wider, the stock retainers don't fit.  Does anyone know if they can be used with the new retainers?

BTW, first post on RCU!

Thanks,
Greg
