For you spring over guys, I have a question, I am considering doing the spring over in the front, and shackle flip, front rear spring mount flip, does the shackle flip in the rear limit the amount of downward travel, when the shackle is on top of the spring like in factory form it seems like there is some droop, but if you flip it does it take away from or limit droop. Another question is if given the choice would you stay with the factory manual trans when doing the spring over and larger tires or go with an automatic trans. I am in the process of swapping in a buick 350 from a 69 civilian truck, could do either trans but would like opinions of guys who may have done similiar swaps. I want to run at least a 40 inch tires, possible 42 inch tires. How do you're rigs handle on the pavement with spring overs and large tires? can you do 60mph? Any infor appreciated, Thanks Fisherman
