i am fabricating 2" lifts blocks and am wondering if anyone knows the inner hole diameter to seat over my strut? (obviously i can pull my struts and measure but im asking because id rather have all my meterials before pulling my struts) i am also fabricating trailing arm spacers to re-center my rear wheels. should my trailing spacers be the same thickness as my lift block? i.e. if lift 2" does it push my wheels 2" forward or is it less? also does anyone know the width i should cut my trailing arm spacers?
