Question about the TRF
 

I have a question about this car/part
http://www.oople.com/rc/photos/works.../OOP_3518.html
This pic is from the Workshop race. I am guessing that this buggy is the TRF. Is this buggy a made into touring car? Or is it manf'ed? I have never seen this buggy, I like it alot.
But my main question is about the hubs/spindles on this buggy? Are there made for it? For the Touring car? Does any one know if they will fit on a set of rear arms for a Losi XXX-4? I am going to make a electric 4 wheel drive truck to play with, using the XXX-4 buggy. When I get it done I will show you some pix.
Thanks in Advance.

the TRF501X is a dedicated buggy, it shares some parts of the drivetrain with the TRF415MSXX but thats it.
