I'm picking up an old thread here, it was brought up that Mopar offered a torque strap on certain applications, it is a metal cable with two eyelets and a bushing on one end and a spacer on the other, MrMopar CHP has this on his 1969 C.H.P. Polara. I was looking at a 1973 C.H.P. Polara and it has two metal brackets on the left side that clip together. So when did Mopar change the design and is this C.H.P. only?
