I remember way back in the early 90's, I constructed an all aluminum 8-3/4 pinion snubber that looked totally stock. It was basically half the weight of a steel one and never bent when hitting the floor under load, but then again it either was not making much power or just not working optimum.
Now I run no snubber with the Dana.

Some cats have made aluminum drive shaft loops but this is one area I stay with either good old steel or chrome-moly like what I have.
