got some new diff casings and diffs of ebay, and fitted them with a set of hd gears in the rear.

i managed to drill the centre shaft with a 2.5mm drill bit, after grinding a small flat on the end. a cen hex pin is a nice interference fit. it drills easier than u would expect, i used a hand electric drill and a pair of pliers... the shaft flops about a bit in the front cup, as its missing the "ball" part of the bone end, but i reckon a bit of fuel hose stretched round it will cure that.

engine mounts are done, but with a 18t pinion on the 47t spur, the flywheel is just catching the diff casing - need a 20t pinion really, but i killed my last one... i may well take some off the flywheel to cure it.

pics if u want em when my cams batts are charged.

still need a brake cam and fuel tank, rx, and thats about it i think. hey i said it was a back burner...
