    Welcome to the forum.

    Remove the fuel line, disconnect the wiring plug, remove the drive, remove the rear motor mounts, remove the side motor mounts and yank the motor. Repeat for the other motor. Y pipe replacement can only be done with the motor removed or slid forward.

        Thanks for the info. The motors look pretty easy the drive is the new thing. But I'll work on it for awhile. Any body got an idea for where to get 2 long blocks?
