rhinopole: The use of any current drop-in plastic spur creates problems: lengthens the diff and needs to use a bearing which is unavailable (8x15x4), and need longer outdrive cup shaft. There are workarounds, which I have tried to do, but everything requires customized parts: dogbones that have different sized balls and pin, or custom outdrive cup that has the needed length while retaining the smaller drive cup, redrilling diff mount holes (not a big deal really), etc. So, I will be using the stock steel spur and a hardened pinion for now. If it holds up, I will be happy. If not, maybe by then Mike will have some type of drop-in solution. Judging by how fast these truggies are selling at my LHS, I think they will be quite popular and there will be many more conversions. I know Mike does have one and he had been looking into different ideas himself.

Riceman: Yeah, I already had to order a new diff cup (the one I have seems OK, but I've been taking it apart and putting it together several times and am afraid the screws won't stay tight) and a new diff mount since I already modded one for a 16mm bearing. IMO, the best bet for things like shocks and other assemblies is just to wait for eBay chopshops to start selling them. Much cheaper that way.

And yes, please do post your conversion (maybe start your own thread so it won't get lost in this one).
