It's a great upgrade, did it myself.

I did the Boom Vader fix where you have the bottom completely welded over, and now have no gas level indicator. So picked up a spare fuel bottle and it too fits in that Burrito tube. So trying to figure how to mount the tube on my Boom Vader as well.
Nice pics!!!!
