HEY, i have recently purchased a ke70 wagon and upgraded from the stock control arms to sigma control arms. I got given tyre rod ends to fit the sigmas but are to short and i can't get a straight wheel alignment as they just wind off the thread. What tyre rod ends would best suit this so i can get the wheels straight? also I'm looking for a 1.5 - 2 inch drop in the rear i want to flip the leaf springs so it becomes a bit more stiffer rather then getting blocks and still having it bounce around, i have done some research and found that the bottom 1 or 2 will drop it around that height but i just want to make sure that is correct before i do it and what are the steps involved to flip them. thanks.
