New to rebuilding. 74 dart custom 318

Howdy, from central Texas. Glad to have you here.
My son's daily drive while in college is a '74 Dart Sport with a slant six. We started building a '74 Gold Duster, but he ran out of time and money (college does that to a young man.)

All good suggestions here, but what I would like to mention, if you are on a limited budget like we were, is to consider only replacing original segments of the wiring that have been hacked up - maybe the rest of it is in good shape. You would be surprised how many cars are being parted out, or how many folks have just pieces of what you need squirreled away from projects long ago.

Your '74 has several harnesses that can be separated into "regions". Identify the butchered wires and what components they serve, then ask here on FABO if anyone has that segment of the wiring for sale. For example, last weekend, my son and I were changing out his column shift steering column to a floor shift column. The wide plastic connector underneath the column that serves the ignition switch split in half. Fortunately, we had an extra harness and robbed the connector from it. Back in business and back to college that afternoon.

Keep us posted and good luck,
Jerry
