Restoration can be fun, sometime I think people go to far. I think eather way, restoring to dealership condition or factory conditions is great, if you have dealership sales recepts showing there mods it can be entered into restoration compitiions in the dealership setting. One thing I'd consider is not fixing everything, example my car is 1972 with white interor the color of the panels have changed color over time and don't match each other, in fact the vinal is close to the original off white, and the plastic panels are tan from age, and the seat covers were replaced. Some people resoring would need to dye the plastic, or fade the seat and color the vinyle, while I like to see the history in the car by not replacing or coloring to match. It gives the carecter and a uniqe style. If and when I'll replace parts with new I'll have them looking like originals from factory or find original parts, but I will now make them match the other parts.
