theres a lot of jy upgrade post available but this is slightly different i have missin parts and busted parts and i scraped a 93 grand cherokee a week before i bought my 94 xj and i can buy back those parts at scrape value so id rather get them than jy prices heres the list same engine
*will the grands front swaybar fit my xj
*will the console direct bolt up
*will sensors interchange ex. iac
*and lastly i will do the rear disc brake upgrade later but will the grans master cylinder and booster work with my factory xj system until i get the disc

Go to the stickys and it will tell you what fits.

sticky answered some questions and said v8 swaybar would fit what about inline to inline or sensors
