If the 190's are serial numbered and like mine carry a model number, does any body have a cross reference as to Dates, 2 pinion vs 4 pinion axle diamaeter etc ?

All 190 and 190XT chassis (bellhousing) serial numbers prior to sn 9001 had small (2 3/4" diameter) axles and 2 pinion differentials from the factory. All 190 and 190XT's from sn 9001 to 23000 had large (3 1/4" diameter) axles and still had 2 pinion differentials from the factory. All 190 and 190XT's from sn 23001 and up to the end, are large axles AND four pinion differentials from the factory. The 2 pinion/ 4 pinion differential thing doesn't mean squat anymore because many 2 pinions got updated to 4 pinion style when there was a failure, so the serial number is absolutely meaningless. The small axle/ large axle is obvious......use a tape measure if you can't locate the chassis serial number.
