I don't think they make them but I'm w/ you an Avenger R/T would make a nice ride w/ a v8 and RWD. Always liked them. I'd guess any fab shop would do it. Or you could try and find a tube car for sale. tear the body off and lay the new shell on it. Buddy has a SB turbo chasis Omni TC3 that started life as a Vega.
