I think the '67-'69 Camaro/Firebird/TransAM/Chevy II distribution block (with appropriate thread adapters where needed) is a better bolt-in possibility.

Randy, I found the kit you referenced here: https://musclecarresearch.com/valve-kit-wagner-amc-dist-switch But, I don't think my distribution block has such parts as they show. The block does not come apart (cannot be disassembled) I did find a distribution block at Jegs that looks very much like the original in my car, for '67-'69 Camaro/Firebird/TransAM/Chevy II. I did order one some years back and found several of the threaded holes for brake line fittings were larger than for the Avanti. The GM block may be usable with thread adapter fittings. Regrettably i am getting too old and feeble to do much with my cars anymore, so my '71 may continue to sit. shown below is the old block compared to the (new) GM block.

Thanks, I was hoping for a less-expensive (much simpler to implement) original replacement valve.

Darn, misspoke again: I meant to say "If anyone knows where I can find a direct replacement for this distribution block, please let me know."

Also, I do not believe my valve is a proportioning valve, but rather it is a distribution block with a switch to light a dashboard warning light if either the front or rear brakes lose pressure. The valve has separate inlet and outlet ports and chambers for front and rear brake circuits, respectively, and a pressure switch between them that senses when pressure is lost in either circuit, illuminating a red warning light on the dashboard. If anyone knows where I can find a direct replacement for my switch, please let me know.

BTW, I've been unable to find an exact replacement for my valve.

Looks much different than the valve on my 1971 (which I believe to be original to the car, which I've owned since the 1990's)

That is one gorgeous '76!

I believe my '80 (sold several years ago) had leather door panels. They looked the same as the seats and had stitching in the vertical seams. Click on the pic below:

Gunslinger: I did not have any luck at Nostalgic when I tried that some time ago, I'll give Jon a try. Silverstude: I am not having any luck trying to look up a "combo valve" on that website, can you give me a link to that info?

I am in need of a working brake fluid distribution block/warning switch (located beneath the master cylinder) for my '71 Avanti. I am not certain what model years the switch was used. As pictured.

Why not clue others as to where that switch is located....

Just... WOW!

They all came with glass covers, but there was a time when you couldn't find those glass covers; today's replacement covers are aftermarket. So if yours doesn't have them, my guess is that the trim "rings" are the same ones used for glass covers, therefore you should only need the glass and the gaskets (unless the owner who made the change substituted shorter screws).

simplistic approach: do screen prints of each page, then send the screen prints to your printer.
