OK, I just tried a few of these out. There was no problem on the wire gauge, but the insulation thickness was a bit sketchy on SOME of the wires ('87 GLHS). I wasn't a fan of how the insulation crimp bent back a bit (see pic). Other than that they fit great. They played nice with the TPA and the tang clipped in the right spot. They worked great with my cheap crimper too. I give them an 8/10.
