Hello...My name is Rick and I am a first time poster. I live in suburban Philadelphia and own two vintage Honda's. One is a great all original 1973 CB500 Four that I ride when ever I can. The second is a 1976 CB400F that I`m restoring after it has sat unused for nearly twenty years.
I am in the middle of putting the bike back together and this is my question.
On the rear axle are two spacers. One on the drive side and one on the brake side. I have them mixed up and need to know which side is which

One spacer is 30mm and the other is 34mm.
If any one can help me I would be most grateful !!
Thanks a lot
