Rear Main Seal leak

I wouldn't say they did it "wrong" but there WAS a better way.
They're a fairly reputable shop here where I live and build some high horsepower engines. Been in business 40 years. But the bulk of their work is on Chevy engines. There's a place called R&R machine in Huntsville, Alabama that knows Mopars and the tricks of the trade with them. I might try using them. If I lived closer I'd have Dan Dvorak do all of my machine work.
