Restomod or Original OEM style?? - Feedback Appreciated!

These are some great insights everyone. I really appreciate the feedback. Just shows there are a lot of opinions and just as many options. Luckily I have the icy winter months up here in Calgary to consider everything and make some decisions. Whatevber I do, the front suspension and steering is getting replaced with new, and the rear will get much better shocks, new bushings, shocks and a rear sway bar as well, at minimum. Will move to a power steering setup, and power front disc, but keep the rear drums. I have an 8 3/4 rear end but not sure on the gears. I have a 4.5 bolt pattern and I want to keep the centerlines that came with the car when I bought it (gonna powdercoat them), so that has to be considered as well.

The one thing I like about buying an all-in-one unit like from QA1 or RMS or whatever is that they are built to work together and designed as a unit, whereas piece-mealing it, to me, always ahs the ability to increase issues. I am sure many others have not had a problem doing it (as clearly described above) but if I am looking for a modern setup that would be the way to go. If I decide to stick with an original style setup, the suggestions above are awesome and save me some time.

As always I know I can count on this forum to give me the knowledge, and the honesty, I need to make this project a success. I'll post pics as things progress. Teardown is the first step.
