So anyway, a Dana 44 would be a good choice for a front differential then?
What does a good second hand unit cost typically Stateside?
What are your plans is said SFA swap happens? Keeping the 8.25 in the rear?
Basically you got 3 main D44's you can use............
One with 4.5 on 5 bolt pattern that is low pinion and uses D30 outers and must use coil overs,the TJ Rubicon D44.
One that is 5 on 5 bolt pattern that is high pinion but much wider then a stock,might be able to use seperate coils/shocks but most likely have to use coilovers,the JK Rubicon D44.
Then the last one is is 5 on 5.5 bolt pattern and is high pinion,can be narrower then stock(EB HP44) or much wider then stock(F100/F150 HP44),will require welding on new brackets but has all serviceable bearings and manual lockouts.You only want '75-'77 F100/F150 HP44 due to weld on wedges and can look up the good years for EB's.
As far as local prices here in CO HP44's can be had for $150-$200,JK D44's run about $1200+,and TJ Rubicon D44's(now rare) run about $800+ without knuckles,axles,or brakes since when they upgrade they must transfer that stuff to there new axle in most cases.Granted the Rubicon D44's will come with a locker already which is either air(junk) or electric.
