I need help, I am 3/4 through header removal and have run into 2 problem bolts. On the passenger side next to the A/C unit bolt is rediculously small, i have ordered a 14mm swivel but tool dealer takes forever, so i was wondering if there was a cheating way. The other bolt is near to the master cylinder (brake), essentially the 5th bolt back from the front, the headers contour around it in an odd way. Finally can I reuse 1 bolt due to my power steering bracket being held onto the 1st bolt on the driver side. Thanks in advance!
