On the MGM YouTube car? Looks nice and brown to me. Guys says that it appears to have all original sheet metal. Why would anyone ever say that unless they have proof? Quarters have been replaced at minimum.
Lord knows that I am all for making your car into what you want it to be, however, I think your car is rare enough, and good looking enough to keep it original looking. I also think it will be worth more money. How many 1970 stage 1 convertibles were made?
I have a 1970 GS Stage 1 4 Speed Convertible. I added front disc brakes(factory). I don’t see how that devalues the car it is a safety feature. I drive the car and it has been totally restored. I also swapped out the clock for a factory dash tach too.
It really doesn't, since those are factory available options, and they're not a huge feature of the car. Those two options are usually value-add, as well.
