UPDATE - Luckily the dealer was able to extract the broken bolt from the frame and I was able to locate the broken bolt in the street (will post photos later). New bolts were installed with the kit and the car is getting a four wheel alignment. Should have picked it up yesterday but, apparently some of the alignment bolts are TTY (one-time use only) and those had to be overnighted.
Looking forward to driving the car with the kit installed to see how much of the fishtailing has been taken out!
