Look for cracks in your right crankarm before you use it!

Well, yeah, at first I thought I had a matched pair, but then when I looked for dates I realized I do not, and the non-drive is not panto! Probably the left cracked, and the right did not because of all the extra material associated with the integral 5th spider arm design.

Thanks!
