That's very interesting and valuable information 3B. Being that those numbers are handed left or right, I wonder if Jim Carter uses those very parts and marks them up for sale on their site. At any rate I just ordered those from rockauto. We'll see what they look like when they get here.

Thank you very much to all of you that responded. I'll post up the results when I get them here and compare.
