Project... 2 pictures below.... In the first, of the drivers side firewall, I know this is a voltage regulator... correct?



In this picture of the passenger side, what is the finned thing in the circle??



Thanks !!

Hey Weasel Diesel,

Your are correct, the item on the drivers side of the firewall is the voltage regulator cover made by Cal Custom (part #40-63). The finned item on the passenger side is a horn relay cover also made by Cal Custom (no part #). The horn relay on the original coupe (and mine) is a 1956 Corvette 913 relay. I don't really know why this is on the coupe as it is not hooked up. Here is a FREEBEE for you. The master cylinder on the origianl coupe can be bought at Napa Auto Parts Item#: UP34404. Encolsed below are some better pictures of these items for you to get a better look at. Hope this helps you out.

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!

hi all!! i put this master cylinder on my car for the clutch,it works great but seems to seep fluid out the top,under the top is a cardboard gasket? and two o rings,do they go top to bottom around the cardboard on the bolt? can i get a new gasket and where? thanks pete

I'll have to look at mine today and report back, but I think the o rings go directly under the lid, but before the paper gasket.

Mine never seeped, so wherever they are in there they must have worked. I'll let you know tonight, in the event someone else doesn't post an answer first.

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!!!!!
