Just got a MPA chassis with all the bells and whistles except the barricade stops. Looking to get just what I need for now. My question is, judging by pictures could I not use one of the "cow gate" wedges backwards and accomplish the same thing as the standard barricade stop? If not I'm going with just a regular stop, if so then I'll pull the trigger on the wedges and use them for double duty. Thanks for any input.
