Run into a bit of a problem. It seems the round on the FFI 1.24 TBs I got are bigger than the hex on the ends of the bars. The hex portions of the bar slide in easily but after a little bit of knocking the bar into the crossmember hex it is f*cking firmly stuck (drivers side), I think because the round is interfering with the hex socket. Was not able to knock it back through from the front side of the crossmember hex today, will try a slide hammer type approach from the back next time I work on it. I tried the passenger side without any tapping and the hex goes easily but it seems to stop up as soon as I get the round of the bar into the hex socket. On the non-stuck bar, I'm measuring 1.25 up to 1.275 in certain high spots, even without paint thickness.
