I read about this in Hot Rod magazine back in 95. One of the big wigs for Ford had a one of a kind Bronco made for himself, using a Lightning drivetrain. He even used the L wheels, but had to bor out the centers on the front, for the hubs. His was the only factory Ford Lightning/Bronco ever made.
What's so hard about repairs on that motor? I don't find it any more challenging to wrench on mine now than when it was stock...just have to remove inlet and/or discharge pipe occasionally, but that's just a couple of hose clamps.
There is a member that converted his bronco to look like a GEN 1 L (not sure if this is the same guy) and it looked very nice when it was completed.
