I did this one for a good friend of mine - it's on a Kyosho truggy chassis, buggy arms and lots of Fioroni.
The intersting thing about this conversion is that pretty much everything fit - with a bit of a tug in a couple of cases! It has the full cage and 'body clips' together just like the Associated!
There's also a Mugen being done by another friend of mine....
It was a FUN project - time consuming (I'm slow and it probably had 10 hours in it) and there are only 2 custom made parts from Kydex - neither of which are likely to break!
