Would you have to flip it upside down because of the gear rotation?
I know you can buy that big $$$ piece from calmini for the first gen rigs and use some bits and pieces from a japanese built 96-98 to eliminate the "shit on the fly".
If you're going to that extent to modify it, slap in toyota axles and have done with.
I have lined up a toy p/u to donate its axles etc, just saving for all the johnny joints and dom tubing to make my four links.
I hope to have it done for "suzican" at ht eend of june.
