Level of difficulty changing 8 3/4 gearing

well you will need a good jack two jack stands a socket to get lug nuts off a 3inch.extension a 9 1/6 socket maybe a small pry bar and a drain pan O and sum oil dri or kitty litter...and a first timer id say 2 1/2 hrs.and on a 1 to 10 maybe a 4..$$just a ring gear 200.00 and another 200.00 to get it set up.But myself I think a 373 gear is not that low of a gear.but that's my thut......Artie
