I'm looking into rebuilding my fathers 2000 challenger 1800 210hp. The gear in the oil pump failed. The block has been re-sleeved, and now I need to replace at least 2 pistons. My question is if there is a good place to get the pistons, rings, and anything else I might need at a resonable price. If any of you have any insight or tips to help me with the rebuild, please let me know. Thank you for any help.
