The carb rebuikd kit illustration, shows the one to use is the one that has sort of a small dog leg cut-out at the end opposite the needle-valve seat assy. Where is the other one used. Possibly a BC? Then I've researched the Old Car Manual Rochester parts list, and I find the p/n for that gasket is 7004480 for just about all 50's carb B's. I don't understand. Can anyone chime in and help me out here? Thanks.

Match the gaskets to the old ones & disregard the extra's.
They say money can't buy happiness. It can buy old Chevy trucks though.

The gasket with the bigger hole is for the early low top model b. The gasket with the smaller hole is for the later high top model b. | | | | | Joined: Jul 2006 Posts: 22 New Guy | | New Guy Joined: Jul 2006 Posts: 22 | Thanks everyone for the help. I just don't understand why these kit makers just don't come out and tell you these things. Seems like such a simple thing to do.
