Safety vs survivor

[chris slawski]

Question for the group. My 69 RS Camaro is currently 100% stock, largely original with about 60k on it. It is not an ultra rare car, other than being unmolested. It has had a poor repaint in original color, some 80’s style rust repair in the wheel houses so she is not a vestal virgin “survivor” but has not been stripped and put back together with wood screws either.
My plan is to make Casper, yes cars name, roadworthy, fully functional and safe. The safe is the question.
Yes a bath is needed in the pictures but that was as found from 30 years in a garage.
The car is a power drum brake car, still all original brake system.
How much of an abomination and violation would it be if I changed to front disc brakes using an OEM specific conversion set up (2 piece rotors, hold off valve etc), as opposed to the metric generic systems out there?
Yes I would be unable to keep the 14 x 6 original rally wheels for drum brakes, but I have already sourced a set of 14 x 6 rally disc brake wheels. Yes I am holding onto the original parts if I make the change.
Thanks for your input as always!
