1969 Dart Build

Guys,

I am doing research on building a GTS 383 4-Speed build with my sons. When this project is finished, it will have little left in original parts, i.e., different stroker B-motor, G-Force trans, sub-frame connectors, torque boxes, aftermarket K-member, aftermarket brakes, mini-tubs, CalTracs, Dana 60, fiberglass body parts, different exterior paint color, etc. Does it matter if I start with a slant 6 or small block model body, or does the BB models have items on them that make it better to start with. When finished, we want it to appear like a stock GTS 383 4-Speed car. Thanks.

Dave
