I'm helping my son in law install a Fass pump on a 18 mega cab dually. Where it says to install is not possible, maybe on a single wheel. The leaf spring is mounted where they say remove bed bolt. Anyone dealt with this problem? Im about to drill the frame but he asked me to post for him.

Ended up installing it in the dually fender, there's good bolt holes there. Yeah I know blow a tire and its history but on a mega cab you have nothing.
