manual rack

i have searched thru the threads and have seen alot of people that have used manual racks from 79-81 mustangs on their cars, but my question is that autozone lists a manual rack and pinion for my car, a 1989 coupe for the same price as the one for 79-81 but is a different part#, is there a reason that the manual rack they have listed for my 89 not work? thanks for any help.
 
dont do it, dont do it, dont do it! i have a flaming river quick ratio rack on my car with the stainless steel steering knuckle and hate it! its a pain in the butt to manuvere around parking lots and infact im thinking of transafering back to power steering and I only have 23 miles on the setup. ill sell it to you?
