Needed: Injector slide hammer (Watertown, MA)

Anybody near Boston have an injector slide hammer that I could borrow this weekend? I've got 3 injectors out and my slider hammer broke on the 4th. I've got another car so I could pick it up and return it. Thanks!

Never mind, I was able to adapt my other slide hammer to the injector using a tie rod end (same threading as injector) and a bearing shell (to hold together the tie rod end and the threaded rod/nut from the slide hammer. I feel like MacGyver.

These injectors had been in there 18.5 years so I guess it's not too surprising that they were hard to remove.
