I just wanted to see if anyone else had dealt with this. My bullet came without a trem arm but I noticed it had the threaded hole. The trem arm from my MIM strat slides in and out because its too small. Theres not much info on the net but I found an ebay auction that listed a squier large thread size 12-24 arm which looks like it would work. A couple of other sites had a 10-24 large size listed but I think they made a typo as a 10-24 should be just as small as a 10-32 like the standard ones. I was trying to find a 12-24 bolt in the garage but only seemed to come up with one bolt that started to thread in but its too short so it bottoms on the high e bridge saddle. If nobody knows anything I will still find out and post up for future reference.
