Help! Quadrajet question

[69 Driver]

When rebuilding the Quadrajet for my 69 350/350, carb #7029207 i neglected to notice which way the baffle in the secondary bores should be oriented. There is a small box-like structure on one side of the baffle in one bore. Does this orient to the front or rear of the carb? It will fit either way. Maybe someone has this kind of baffle and could look at it to see which way it orients...

Also, i think the date code is 0393. Does that mean it was probably a replacement unit built on the 39th day of 1973, even though the model number is correct for this engine? Any comments on that?

I have the Doug Roe Rochester Carb book, and the pics in the book show that baffle to be just a flat plate with a notch out of it at the top inner corner. I can post the picture if it sounds like what you have.

Thanks Gary, I have the same book and have looked at two or three of those photos and the one in the photos does look flat. Mine is different with the "box-like" structures on one side of the baffle - one in each bore. If no one out there knows which way it goes, i'll try it both ways and see what happens...
