I just got a prt 4x8 alpha with an ATC and an air drill. I had to disassemble most of the wiring harness to send some stuff into Shot Bot. Before I hook everything back up I was thinking about adding e-chains to clean everything up since the existing arch is broken and will probably break again. I looked on ebay and there is a lot of low cost e-chains. Any advice on size and style would greatly be appreciated. Thanks
