It was at a pull here kind of local to me last night. I put one of Tony's spool and axles in my truck back in 2009, right after he came out with the 38 spline. I've been running it in my street truck ever since, waiting on a locker to come out. I had a customer ask for me to get him a spool and axles, I told him I'd trade and eat some of the cost myself by ordering the locker instead of spool for him. I switched the locker into my truck and find out one axle is shorter and Tony's current stuff uses equal length axles. I called them and at first, without talking to Tony, they were unfamiliar with any differences... After talking to Tony, I have one of about 6 sets in existence with one axle shorter than the other. They changed the spline location in the spool to accommodate equal length axles. And it was the customer's first hook. It broke out the axle bolt cover right where the o-ring is cut into to seal the full floater axle, it looks to be about 1/8" to 3/16" thick at that groove. Of course the customer has a hook next weekend, so I need an axle and cover ASAP!
