So my T56 parts order was supposed to show up last Friday. It did, minus a 2nd gear and billet 3-4 keys. Guess what goes on the mainshaft first? If you guessed 2nd gear, congrats. You won yourself a beer from your fridge. So Monday they check and proceed to overnight the parts. Got them yesterday, all is well.

I figured the above mode of failure was more preferable, so fresh "billet" keys went back in. I figured that this must be the way it is. Until I found that article. Tomorrow I'll be calling Rockland, Tick, RPM, and anyone else worth a shjt to try and get a consensus on the billet key market because this Corvette box is a way bigger asspain to pull than the Camaro box, which is why I used it for practice in the first place. I don't want to be doing this again any time soon.
