I've been messaging the guy I ordered the wheels through for the past few weeks/month and never really got anywhere. I've been too busy to really pursue it with any seriousness until today. I dug up the original email I sent to him with ALL of the measurements on it, sent it to the guy at BC forged and copied in the dude I ordered them through.
Within minutes, BC forged called me to talk about it, said they never received all the info I had sent to the guy. Had they seen that, something would have changed. At any rate, they're committed to making it right, one way or another.
So, this evening Im going to go test fit a fox-length axle in there and see how the wheel fits in the wheel tub. If the axles work, they're going to reimburse those costs. If not, they're going to look into ordering me new barrels with the correct offset.
