http://www.teknorc.com/product_info....8a217800d142dd What about the Tekno's? The front and rears are a little different, so maybe 1 would work better.

For my Slash driveshafts I need something about 1-1.5 inches longer then stock,I've never measured. But I guess at this point I could use the Tekno outputs, and carriers, and just mismatch the rest.
