I've been checking out the 91 extra cab that I just got, and the driver rear body mount is badly rusted. Has anyone fabbed a replacement mount that can be welded in the original spot?

 

If making your own is too much of a task, try contacting www.blazenoffroad.com or www.ruffstuffspecialties.com
Between the two, i'm sure one of them might have or make what you need.

Or just find a junk yard with a wrecked x-cab...cut off the factory body mount bracket and there you have it.
