Give me a couple of days to fish them out, and I'll be glad to share pics of 2 original 4053's, 1-68, 1-69, plus the balance of parts from an early Holley 4053 reproduction I parted out (bought the carb in the 80's when they first started repopping them, sold the center section, 4 digit date, and kept the bowls, throttle plate, metering blocks, and all small parts intact to rebuild my 4346 for the 375 horse).
I really wish the Holley Custom Shop was still in Springfield, TN - they used to take your Holley in, completely rebuild it, replace any and all worn parts with new (proper part #'s !), restore and replate ones they didn't have, and bench it and send it back to you for about $400.00. I don't know if they still offer that service, but it was great while it lasted here. They closed that location down, moved it back to Bowling Green years back.
