I really don't want to cut up the car, so I was trying to see if it is feasible to get things lower. I don't want "the worms" LOL

Neil, I am thinking that center link is the lowest piece as well, wondering how close it is to the pan. Won't spacers interfere with suspension geometry, steering, etc.?

I have a 42RH just rebuilt and upgraded ready to go in case I don't go with the 8 speed idea. I'd rather use that than a GM transmission.

Thanks for the input for the shaker question.
