what? no diff cup problems? driveshafts are ok? hmmm maybe u arent driving it "properly"
nah seriously - no diff probs at all mate? with that motor in, i reckon u could clear the humber and drop it into my back yard! my little os 18 has given me enough transmission troubles tho - so i wouldnt try it!
where do u take ur truck? u mentioned a quarry - do u bash down there with anyone else? i only have touring cars to run over in cleethorpes... fun but they dont like it much. i would love to see that thing run!
