matt's ok with the z's but there are somethings he's weak on, usually the shit but sometimes really brief and undescriptive to those who don't/didn't have a clue as to wtf he was talking about on these cars. i have an 84T myself, matt is your best bet but be warned you better be prepared for briefness. sorry bro don't mean to bash you but it's true. all gravy and sh** but true.
