I posted this in the Fuel System forum and never got a look and its been on top for a while...so I'll ask here because there is more traffic here.

You're in luck I have a Holley 6947 collecting dust Casting number D5TE-9510-EA
Carb is 95% complete. Missing primary jets, Accel pump housing, and primary fuel needle and seat. Throttle shafts are tight free and smooth, every thing operates as it should. IIRC the carb has low miles (less than 40K) and was pulled off in 77 or 78 and had been rebuilt once before being swapped out. Shoot me a PM if you're interested.
I have got hard to find parts right from Holley engineering. But it isn't always what you need. The last one I did was an over the counter GM service replacement for a 67 Chevy 425 horse 427. It was a bunch of parts and gaskets, 75% of which weren't even for the carb I had. Like they just went down a parts aisle and filled the box.
