PJ, sorry mate, the old eyes aint what they used to be. I was looking at the engine mounts, they kinda look like hinge pins rolled together (if you stand back and squint!!).
The full truggy conversions include a longer chassis and different shock towers aswell as all the drivetrain shafts and assorted other necessities. The cheapest I have seen a JT truggy conversion kit for is £135. Of course it is perfectly possible to stick a pair of HPI nubz, a larger clutch bell and a 1:10 stadium shell onto a buggy and bob's your uncle! All down to budget and when it comes to my Christmas present, no price is too great!!!
