Spring Relocation

Bushing size depends on what springs you are using. You need a bushing with an id for the size bolt used for the rear hanger to shackle bolt. Yes you use the existing hole and enlarge it for the bushing your using for your shackle bolts, as in the sent pic you can reinforce it with a large washer. Most relocation kits come with the rear bushing unless your making your own kit. Just make sure your bushing matches your shackle bolts.
