I'll second the recommendation for Steve. He has done some work for me in the past and knows his Mopars extremely well. I haven't spoke to him in a little while. It was right after the Rettig Bros machine shop (in Modesto) closed. Between their machining and Steve's building, it was a tough combo to beat. They all campaigned Mopars in Div 7 NHRA. He always does side work when he can and last I heard, he was with a race/machining group out of Stockton. The phone number listed is what I have in my address book as his cell #.
