Spray, this is on the 48 coupe man. I have nothing to it, no tires, no suspension, nothing. I have the upper and lower control arms bolted to the spindel. I wouldn't doubt that this thing is the wrong size because if the guy can't even keep bolts in order or even keep bolts AT ALL then I bet he screwed this thing up. It seems to be pretty accurate in measurment besides that for some reason the leveling is off a bit which kind of pissed me off.
