my heater core cracked, got the new one in the mail today. i live in fargo so theres a pretty good chance ill need some heat sooner or later, my ac's all disconected and removed. what i need is someone to give me a decent instructions on how to change them out. its a 93si with a b16 sirII swap, i did the swap myself so i think i could handle a heater core, please help, the more the better. thanks everyone on h-t helping me not freeze this winter, also, what is my lsd going to be like in the snow? fun i hope?
