I am new to the forum. I looked for a thread on this and didnt find one. 6.4 cracked a piston and now time for a rebuild. I called River City Diesel and got a quote on parts and planned to buy everything needed from them. Sales sent me a quote and I was very pleased with our correspondence. I accidentally deleted the email, so I called them to place the order. All of their phone numbers are disconnected. Looking for a new vendor to buy from. Any recommendations?
