Fairly new owner of a 70 RR. Looked at the casting numbers on the rear end case today; Numbers are
4
2881489
9
Means I have a 489 type rear case. What does the 4 and the 9 mean? And the 9 has 3 small 000's under it. (The rear end has a 3:91 gear in it now)
Not sure about if it is a Sure Grip or not......when I turn the right side rear wheel the left side rear wheel turns in the same direction......
thanks
