I'd skim over the 2.5L engines, and the Dana 35 Rear Axles, unless you find one in just absolute mint condition.
(4.0L w/ Dana 44 is significantly more desirable in many ways)
And the Dana 35 rear axle is generally regarded as just being a shit-gamble.
Some people beat them for years, some blow them in parking lots.
Dana 35 can be upgraded to a Super Dana 35 and then be just as capable as a Dana 44. Andy
