i plan on doing it at some point as well. if you go with a 3/4 ton up front you might as well do the same in the back same with 1 ton. the dana 44 out of the 78/79 bronco is the same lug pattern that you have stock where 3/4 and 1 ton axles i believe are 8 lug so if you went with that then you could stick with your stock rear unless ya didnt want to. the solid axle swap would give you wayy more flex when offroading. for the lift you would just have to use the front lift parts from a 78/79 if you went with a kit. from the research ive done the ttb coils are alot stiffer. theres a bunch of threads of other people who sas their truck, so look at all your choices and go with what you think you need
