Is there differences between the 1986 and the 1985 Tri-z swing arm.If there is what are they and does anyone have some pictures or an easy way to tell them apart?
thanks

The 86 runs a larger outside diameter pivot bearing (by 1mm) and has extra gussets on the top side, ill see if i can get a few pics

Thought the 86 has the smaller bearing, 85 large bearing?
