Do you know what #s your looking for? I have one that I just took off of my 400, my mechanic said it was a carb from a 403 he rebuilt it a couple of yrs ago. Has a couple of hundred miles on it.

The correct numbers for 1977 were 17057253 and 17057553, depending on high or low-altitude emissions. The '78-79 equivalent numbers would also work fine.

Here's just one ad that came up, although appears you could end up with any number, but one that works with those numbers. Also a stock replacement rebuild, as per anyone that can recondition a Q-jet and has that number in stock.
