I have a 1990 toyota 4 runner with an automatic trans..i was going to put a 3" body lift on it but alot of people said to put ball joint spacers on it instead..can u please tell me where to get these and how big they have to be and also do i need to do anything else after i put the spacers on it? Will i be able to run 33's or 35's with just the ball joint spacers? Thanks for everyones help
