boys it works a treat. takes a bit of measuring and cutting to sort it out but works grand. used that 19mm pipe insulating u get for copper pipes and hacked it up til it fitted sweetly round the wheel then sprayed it with glue (same stuff u use for sticking carpet down) then fit the tyres over it and bosh.
had it out for a wee play in the yard goes well and i prefer the set up, I'm running 500k diff oil, this is the 3rd diff iv put on it, think with the soft wheels it was gripping the tarmac to much and ripping the cogs apart.
problem is i think the clutch spring is starting to go, sometimes it wont idle and will creep forward and then when u go to start it you can see it tryin to spin the spur gear. its not completely gone but its gettin that way......................MORE MONEY
