68 Valiant Hellcat Swap

Sublime one, do I see a scat pack next to the cuda?.... I have a sublime hellcat, so I have some reference on some of the " factory" parts & where they go, and yes, the problem is trying to find a less expensive way to build this car, , I'm painting my cuda sublime also...love it!.... lucky for me I'm going race car style, no power steering, no power brakes, no wipers, 2 seats & a roll bar... Another question, how do you get a tach signal off the hellcat pcm to run a Auto meter tach?
