NEED HELP FAST VERY URGENT about rims and tires

hey, i need some1s help big time. does any1 know what the wheel size it in a 1995 impala ss? i dont think im saying it right. im talking about the part of the wheel set up where the holes on the rim fit into the bolts sticking out of the brake rotor. the thing where you put the lugnuts onto the rim to keep the rim from falling off. if some1 could tell me how many there are and how far appart each are from each other. im getting custom rims from a friend and i want to get them for an impala but i dont have the car yet but i am absolutly planning on getting it. so can some1 tell me what spec i need to tell my friend to see if these rims will fit the impala. thanks

its called a bolt pattern :smile:

and for a 95 Impala SS the bolt pattern is 5-127
