Heys guys, does anyone know if the fatter bushing(part # 68036) goes on Firewall mount and the thinner one (part # 68034) goes under the rear frame mount? Reason I ask is I was double checking the location of my Prothane body bushings and the guy at Prothane is saying the thinner one goes under the firewall. But I thought the fatter one went between the body and the firewall.
