I installed the screws that came with the Kit. In a long shot, I emailed RPM to see if they were planning on any a-arms for the Durango cars since they made the wing mount for the DEX8 and their reply was pretty much that they haven't done so well with Durango parts in the past (I believe he meant people interested and buying) but he was going to passed to the development department for review. I guess if more people show interest in Durango components chime in and show interest they might produce quality a-arms for the Durango 1/10 cars. I hate that after one run I got broken parts and the potential fix is not to install the droop screws.
