hi guys maybe you guys have a answer. the older mpv center edge was two pieces of 3/8 rubber with two steel plates. they work good for a while ,until where used up . then western change thier design to two steel brackets with one 1inch piece of rubber edge. when it real cold outside the tend to break off in some snow plie. i liked the old design better. can any one tell me what would work better/and where i could buy some rubber for the center. thanks for your help.
