hi wes thanks for the info. My car had the springs moved in before i bought it and the rear end is supposed to of been shortened. but i do not know how much. My car has 15x8 weld wheels and m/t 275/60/15 tires on it now. looks like i can move the rear back 1-1/4 with the extra holes in the spring mounts. here is a pick that shows how close the tires are now. thanks Bobby
