I also found that where the collector comes out on the drivers side, it is 2 1/4 inches off center from where the crossmember is designed to allow the exhaust to go by. what did you do in order for it to fit past the gear box? I don't want to beat in the headers. Also for anyone that didn't know, we checked the levelness on the header flanges where it meets up to the heads and it was quite out of level. We had to sand down the middle a lot. i can understand a little out of level in the middle so where you can draw up the end bolts but this was rediculous!!
