I did some searching here, and came up with nothing of substance.
I am trying to figure out which secondary hanger part number is for which letter code hanger.
This gets further complicated because:
1) The part number assigned to the 'secondary metering rod holder kit' (which contains the hanger and small screw) is just that, a kit, and not the hanger itself.
2) according to my Doug Roe Quadrajet book*, on page 251 is says that the only service hanger is part number 70354522, which is the 'V' hanger.
* = the original good one, not the latter condensed garbage one; HPbooks-35; mine shows a copyright date of 1973, but is also a 12th printing.
I see that Ethan in his attempt to help people has said several times that the hanger for a given application number is the '522 number - but he says it's a 'K' hanger, which confuses me because it contradicts the information from the Doug Roe book...
I have a small collection of Pontiac Quadrajets, and I have collected parts and literature, some of which is the yearly Rochester carburetor chart books;
This book shows a '522 for all four 1969 Pontiac Quadrajets
I have a nice little collection of these hangers, and I have been as my schedule permits, fixing up Pontiac Quadrajets to be correct for their original intended configuration, so this begs the questions;
1) Does anyone have a cross reference for Quadrajet secondary hanger part number versus stamped letter code?
and
2) Does anyone know the original letter/number code for the secondary hanger on (oh lets say at this time) 1969 Pontiac Quadrajets?
My principal focus is on 1968-1974 Pontiac Quadrajets.
