Huh, interesting. I’m running KYB gas-a-just with Hotchkis lowering springs rear, cut coils front. Fresh, smooth pavement, beautiful. Our normal crap Indiana roads, very harsh. Would be interested to learn your experience with Koni’s if you go that way.
It really depends on how stuck in the head about being "original", if your is 100% original down to the dated plug wires and only driven to shows to be judged by people who know what to look for and will hit you for points on not having those things well then yeah go for the ones that came with the car, as far as what "we're supposed to be doing" ?? let's relax a little, myself I hate "restomods". I like a rake, I run air shocks in the back and gas charged in the front, I don't like the way they sit from the factory nor how they drive, if someone looks under my car and says "gee pal you're running the wrong shocks" I say I come to shows to see other cars, I don't need a $2 trophy to stroke my ego.
