Bad starter Grand Voyager

I have a '99 Grand Voyager SE 3.3 V6 and my starter went bad, were I can buy a used ( new) starter webpage or telefon number and how hard it is to install it myself. I mention I have no manual for my car.
If you now exactly the model nr of this starter please let me know.

Thank you,

Gabriel

They are not hard to change, disconnect the battery, disconnect the wires to the solenoid, remove the bolts holding it in place and remove the starter. Make sure you label the location of the wires to you get them back into their proper locations. To replace use reverse order. To find one go to car-part.com and search wrecking yards across the country. Prices will vary so shop around. If you want a new new one go to Autozone.
