Not sure how this is relevant. That kit is still in production & its on every mac truck. The RBRT set runs $350 all day & if you pay that then your a sucker. I was just simply showing anyone who comes here at present time like yourself an alternative.
I was able to snag this set from my cornwell dealer for $200! Little difference between the 123pc from mac but its all the RBRT, just renamed Gripedges RPT version. So worth!
