built right fabrications also known as "the truck shop" in san diego, fabricated a tranny mount for my buddy's 4runner a few weeks back, turn around was less than a day.
You guys might want to reach out to them and see what they can do for you if you are serious about this.
Their fabrication side of the business:

I have no relation to them other than being a loyal and royal pain in the ass customer.
