Fabricated engine mounts have been available for smallblock V8s for years, but not for 4.9Ls, which are just as likely (if not moreso) to break direct-replacement mounts (including Ford/MotorCraft). So I designed my own, using the same Energy bushing set that the V8 version uses.

If you want a set, e-mail me through my profile here or on one of the F150/Bronco discussion forums I use.
