Yea, I believe they went to 50:1 in 1964 and later, but truthfully, there isn't any difference from your motor to a 64 model......except maybe paint color.

But yes, they recemend 24:1 on that model. 5.33333333333 onces of oil, to each gallon.

Oops, you're right. My bad. 63 was infact the last year of the 10.
