they are made to be used with drop spindles. If you want to keep the stock spindles just modify the stock stuff, bolt the balljoints ontop of the arms and pie cup the uppers.
i have the toyota ones from cando for my mazda they came with drop spindals it cost me like 1250 bucks they were only made to lay with a 20s is all i did was pocket the frame some and trimmed the lower plate a little on the lower arm so it wouldnt hit the frame and i have 22s on mine
Everything Steve builds it top quality ... if u need his arms to do more then he made them to do he will tell u how to make them work
