turntable

i have a pioneer pl-51 direct drive turntable i bought back in the early 70's. the last time i used it was around 1990. it worked well then. my grandkids were playing with it around 1997 and the needle broke off. i still turn it on every now and then. it has a 'grado' unit on it. if i buy the replacement stylus for it would it be ok????
