I bought a 88 260e A few years ago and have been happy ecept all the repairs the latest cost me a new caliper to break off, I tightened a wheel bolt to far and as soon as i hit the roas and went fast the bolt hit the calpiper and took it right off bolt tire and all, now i realize the car i own has 2 differnt size bolts for the tires i bought them and they were all spaced right and worked fine until i stated repairs and rotations now the bolts area all mixed up and i notice the difference between the two what is the most economical way to fix this, can a gararge install them so they dont go too far or should i just buy all new bolts
