ccsial,
I have a recommendation,but it may be too far for you. I live in Chicago and had a 12valve. I went to Scheid Diesel in Effingham(1-800-669-1934) three or four times because they did good work and were trustworthy unlike my area Dodge dealers. I no longer own a Dodge,but I still use them for aftermarket supplies. They also have shops in Indiana.
