I installed the prothane 1" body lift. it was nice because it replaced all the old parts...it $145 but well worth it over the puck versions.
I did need to get a different bolt for the front center bushing. was .5" to long and could not be tightened without pushing up into the grill.
no real need for a write up to do the install. it will take a couple hours if you are by yourself.
replace all the bolts, pb blast a needed, with the longer bolts in the kit. install them enough to hold body in place but allow you to lift body off frame.
then lift body off frame about 1.5" on one side, replace bushings and repeat on other side. leave all bolt loose until al bushins are swapped.
you will need to do a motor lift at the same time or relocating the fan shroud.
