I have thought about putting thew Magnum 500 rims on the car. Will the 15 inch rims make the speedometer read off. It has 14 inch rims on it now. But then again everything on it is stock so I kinda want to leave the wheels origional too.

 

Good wheel choice. The speedometer shouldn't be off unless you run taller tires. If you run something like a 215 60 15, you should be fine. You can always change the speedo gear if need be. They are only a few bucks.

 

I know this is an old thread, but I thought I would share a picture of my 69 Mach1. The paint was very faded on this one, but absolutely 0 rust.

 

My Mach is also supposed to be Acapulco blue, but the PO had it painted gulf stream aqua.

 

Here is mine
