There are tons of low mile 19lbers out there, I probably have a few sets if I look,lol.
I'd at least replace the o-rings on the injectors thats usually the only thing that goes bad often on older cars. Lube them up with some vaseline or something when you stick them in so you don't tear them at all.
The TB is not worth the $$ really but when you get some extra $$$ let me know I have a nice Accufab polished 65mm I am going to be selling.
