I'm looking for a vender in NC or surrounding area that sells and/or builds performance SP/VP T-400 to be put in my 68 Riviera with a 3.42 posi rear that I will have some fun with as a local driver. Are SP kits available that any trans shop can install. I like the idea of 2 or three different modes one can switch to :laugh: :grin: depending on anticipated demands. Would you recommend deeper first and second gears as I have seen available with the 3.42 rear that I doubt will see a dragstrip? I'm just hungry for a few kills here and there.
