Put you a wanted ad up when you find out for sure which arms you need and for the blade holders too. I'm sure a member here has some. Maybe you can get a deal. I have an extra pair of early A arms, but they won't fit yours.
I found some on ebay to but I'm waiting for that one expert to chime in with so I can know for absolute sure what IL need lol. I'm sure there are a few guys on here that will have the parts for me. I'm never disappointed on here.
