I have a 4.2 that had a oil leak, pulled the oil pan and found one of the main bearing bolts broke laying in the bottom of the pan. no problem i got an old block i will just get one of those. The bolt will not fit it is a 1/2-13 bolt the one that broke is 7/16-14. Checked everywhere trying to find main bearing bolt of that size no luck.I know the motor is a 4.2 because the number on the block has the letter c in the number. What gives?
