Engine silver top

silver top

Couple of questions before I send the money to get the silvertop. How easy is to get parts in your local autoshop. example: spark plugs, oil filter,timing belt or chain and also to those of you who swaped would every thing else fit alternador, ac compressor and belts, and header . 1993 Corolla. I asked since everywhere you go they ask for the year, model, and engine of your car. Would I just give them the year of the engine and the model?
