Heads up Help for you guy's about 5.7

Just a heads up for you guy's--when I did my conversion,Now 4 years ago there wasn't much in the way of aftermarket choices as to where you bought parts.Don't forget your local dodge dealer!!!!!!!!! I did not have connections when I started my project but got to know the local parts manager because of ordering the odds and ends that i needed through-out my build,Here is one I need at the moment: Rear main oil seal from dealer $18.95---From Arlington $93.50--I called Arlington about the seal to see if it was different in some way and the answer was "NO"-
Just wanting to help some of you guy's save some money--Steve
