They were close enough that I was able to lube them up with PBlaster and force them in since the grommets are rubber. Also, the driver's side of the bottom tank was made in such a way that we had to cut the driver's side end of the bottom of the radiator support to make it fit, and the bottom tank was so wide front to back, that it hit the front ends of the frame rails and kept the two nubs on the bottom tank so far away from the grommets there was no way they would go in until we also trimmed the ends of the frame rails up. .
