welcome to the club! :waving: you wouldn't happen to have any photos from back in the day would ya? we're big suckers for historical things like that. :D
hard to beat the rodeo/passport rear 44. matches your waggy front in width and pattern and has disks and 4.30 gears. should easily be able to sell your MJ 44 and get one of these plus some cash in your pocket for new brakes on it. :D
even if someone had done the exact same thing, there's no telling the exact lift you will get because it all hinges on the condition of 25 year old leaves. only way to know for sure is to try. :thumbsup: I'd wager about 3" depending on how many MJ leaves you use.
both your numbers are too high. :D I've recovered 3 sets from junkyards over the years for $30 a pair and the bushings have all been in great shape. car-part.com shows some as cheap as $50 for a pair in alabama. the pullapart near me sells trailing arms for $22 each with core charge.
