Hard to believe none of the gears were chipped. Did you actually look at the gears?
I wouldn't be too happy with a shop if one of the bolts fell out and broke through the diff cover.

Adam from Z1 Performance said if anything is chipped or messed on the gears.. the rear would make a noticeable howling.. since i stopped immediately at the sound of grinding the lose bolt didnt have a chance to damage anything. even if a future problem arrises, Japtrix said they'd cover the costs involved.

Glad this worked out. (I'm still trying to figure out how they knew the bolts were torqued to spec if one was launched through the diff and the other was laying on the bottom.

Yep Roger and I spoke a couple times on Friday. Once before he had everything disassembled, and then once he put it all back together. Glad to see you dodged a bullet from the sounds of it, and that you're back on the road

the Z was towed to Japtrix on friday. Roger (shop owner) called back later that afternoon with an update. a bolt had come loose and was flung through the rear diff cover causing the golf ball size hole. since the hole was towards the top, the oil had a chance to stay somewhat stay in the diff, meaning it was never run dry. that was the first zaboom.. and the second was the rest of the bolt getting caught on the LSD and rear cover. when he opened the drain plug almost a quart of oil was still left and one bolt came out with the cover removed. none of the gears were damage.. he cleaned everything up, placed a new cover on, and oiled up the diff. after 5k miles he wants the car back for a rear oil change. the car is giving no howling noise and driving great! Japtrix is a very reputable shop and this experience started a long term relationship with the shop. they covered everything and my only expense was the original tow from the street to my home of $100.
