George, how did you remove the dustcaps? I think there is or once was a tool made for these, but I've never seen one. Looks like one could always use channel locks, but that might scratch up the dustcaps pretty badly.
As I recall the TA pedals were unavailable for several months in maybe 2007 while they supposedly replaced the dies (or moulds) that were said to be worn out, which was blamed for the voids in the bodies you describe. I had some made just before that that had the poor finish you describe. I've bought a couple of pairs since that interruption, and they are better, but I'm not sure they are up to the standards of several years ago. I've not yet found a pair that won't go into BSC cranks, but they might be lurking in my parts bin. Other than just a screw up in manufacturing the only thing I can imagine is that these oversized threads might be made for cranks that have been stripped and rethreaded to a larger diameter, like when one installs helicoils to repair cranks. That seems a real long shot, since there can't be much market for a pedal like that. But TA has made some pretty unusual stuff, like special cage plates for riders with one leg significantly shorter than the other. But no matter why these were produced, it was a definite screwup to allow them to get shipped and sold as BSC (or now ISO I guess) pedals.
