Default Single Booster Quadrajet
Anyone ever see a single booster Rochester Quadrajet with no number stamped on the side?

Does this carburetor have a spot for a round tag on the side?

FWIW.......I have had many 69 SR Quadrajets with partial numbers or no numbers at all. In fact, I have a 7041263 SR that has the "6" stamped over so many times it is unreadable.

Just pulled out my 7041263 after years in storage. I was mistaken about the number 6 being stamped multiple times. It is the 3 that has been stamped over. The bowl has all the vacuum ports, so I am wondering if it might be a 7041268 instead.

All factory 1971 single booster units fuel bowl has the same 7042572 cast # on back.
All but the 7041263 have the same secondary stamped # beneath fuel inlet.

SR 7041263 bowl have #7044603 cast on back, no secondary stamping.
