Well i managed to get the front end narrowed and the XXXT-NT front bulkhead swapped over today as well as i narrowed the rear end with a few different parts than i used on my other Losi.
For the rear of this truck i used all GenII trans parts and i will explain what i did. Since the GenII is wider it makes it a little easier to narrow down but since i have a GenI trans here is what i did.
Parts used for this build are MF2 VLA hubs,MF2 GenII axles and GenII trans outdrive cups.
Since the GenII stuff is wider i had to machine 1/8 of an inch off of each drive cup to allow it to fit in the GenI trans case.
With this mod done and the VLA hubs on the outer hole the axles are now the correct length and do not bind or want to fall out of the cups.
Here are a few pics of the truck and the mods so far.

Here are a few pics of the finished diff.
The first pic you can see the silver spots on each side is the material
i took off of the drive cups to allow them to fit into the GenI trans
case.
The second pic shows the difference in GenI and GenII trans parts.
The GenII cups are on the left already installed on the diff and the shorter GenI cup on
the right.
