Hi guys, this may be posted somewhere, but I thought I would pass this info along. Helm Inc. sells both products to the dealers, (unless the dealer has it sitting on a shelf which is not likely.) It cost about the same, but I got both without going through the shop and waiting the extra time for the dealer to order, have it shipped to them, and then re-shiped to me.
I had an online shop order me one, mess up the order, re-order, got the wrong one, then they told me the part # had changed! (which was not the case.)
So it took almost 5 weeks to get the wrong part. In their defense they did offer to have the manual picked up and give me a full refund.
