Project American Graffiti Coupe

You may know this already but just in case.....If you're using a standard Ansen or similar peddle assembly, don't forget to swap out the internals in that master cylinder. The Chevy unit has the brake internals (which includes a residual valve) on the left and the clutch internals (without a residual valve) on the right side. You need the brake valving on the right side with an Ansen setup so you'll have to remove the "C" clips and swap the internals side to side. Its a simple 5 minute job. That said, replacements from NAPA have been known to come with residual valves in both sides and your clutch will not work correctly with a residual valve. Why Chevy reversed it in their linkage assembly I have no clue.

Cool project, always liked that coupe.Work is lookin good.

Hey Rufus,

I did know about having to switch the internals around but I didn't know that about the Napa master cylinders. THANKS for the heads up as I will be paying more attention to this now!

Thanks Pro53! I am trying my best at getting this coupe just right. Rick

Today I finally finished installing the roll up rear rear window. This is the one thing that is different than the original coupe. The original coupe just a piece of plexiglass nailed to the wood during the filming of the movie and today there is nothing there. Well with this being said I thought that I should install the rear roll up window as to make it at least look 32 correct. Hope you enjoy the photos!

Just in case anyone wants a similar master cylinder but doesn't want to swap the innards side to side, International pickup trucks in the 60's used a very similar master cylinder and the brake and clutch ports are in the right place.

I'm using the Chevy one in my 27 but I flipped it around 180 degrees, so the clutch and brake are in the right ports. I'm sure some will say a single chamber master cylinder isn't safe, but I ran this one for 7 years and it was flawless. In fact I'm putting a new one from NAPA back in the rebuild I am doing on this car.

Oh come on now. We know it is purple. But it is a good cause. I saw a bumper sticker that even my wife liked - Save the Taa Taas.

Something is starting to look pretty familiar out in my garage! I know I have seen this car somewhere before, I just can't put my finger on it. Maybe it was someplace called Paradise Road???? ;) Wait till you guys see what I have in store for you tomorrow!!!!! :3dSMILE:
