are you talking about a Toyota? if so it can be done without spindles for sure hit up sadisticiron (that's his screen name on here) he layed out his yota on 20's with stock spindles and he still gets tons of lift!!!
No its an Isuzu pickup, I just got it for a work truck and I have all the stuff from my rodeo here so Im gonna bag it, I layed my rodeo with stock spindles but it was way more work than what Im gonna do with this one,.
The notching of the frame on the 89 will not cut it. your ball joint will only flex so far & notching the frame will not help. My ball joints stop it before my LCA even touched my frame. Depending on what size wheels & Tires you will be running you might need drop spendles.
