ARP rod bolt problem

I know a lot of you have arp rod bolts installed. Well, I just got off of the phone with the machine shop. He said the arp bolts lack enough thread to tighten down on the cap. 1/16'' he says. And wasn't just 1 rod, they tried on all of them. I spoke with an arp rep, and he seemed very arrogant, like they never make a mistake. He is supposed to call me with their dimensions of what they are supposed to be. But I haven't heard from him yet. Another wrench in my already tight deadline. Anybody else ever ran into or heard of this? Rods are stock common rail fracture cap rods if it matters......
