polyurethane bushing help

I'm installing poly bushing on my ss springs. The kit comes with bushing for the big eye and small. I'm also using the offset mopar shackles. The problem is the large bushing fits the shackle. The small bushing fits the eye. I need the big bushing insert in the small bushing. Anyone ever drill urethane out larger? I have the right size bit, just a little nervous about screwing it up. I haven't found a bushing on line that works for this combo. Any ideas would be great. Russ
