Just been reading up on swapping parts, really good thread in the giant scale forum on the fs racing 4wd mt, along with parts interchagability with MCD products, I see that when you clone a clone,you'll eventually end up with a better clone...lol.. the last post was in 2010, but it did give me a new insight for parts sourcing, I just need to follow up with whats currently available and from whom, will update what i find soon....MPB
