LOSI double jointed CVD will not work on VDF without modifications, not straight up swap. For one bearings in steer knuckle on VDF would need to be replaced, LOSI shaft that runs through the bearings is smaller in diameter. I have both chassis, I'm going to check this out. Concerning the spool, I just locked my diff with 3M double sided tape, stuff works like a welding machine! Front one way for this chassis can be found on ebay for about 50.00 bucks, one guy had it on there the other day for 30.00 bucks!

I have been putting some track time on the JRXS, starting to drift it like a champ, just a few more tweaks needed.
