I don't get it - the best part of doing a retro project would be LOSING the ABS, airbags, & power steering systems. It's more interesting to learn braking limits, safer to use belts properly, and great to FEEL steering response! The changed power-to-weight ratio would be the big, fun plus. I'm guessing you might also need to consider suspension work to compensate for the change in balance and weight - for safety & ride quality (?).
