Vacuum Advance Part # for '41

Recommended Posts

The original part number for the 1937-1946 Delco distributor vacuum control was 681-H according to my Masters Parts List for Buick in 1947. I doubt you will find many with that number as it has been superseded a few times since. In my 1957 Master Chassis book it lists under group 2.410 part number 1116065 as fitting all 1937-1952. That should make it fairly common and easy to come by. In doing a little research I discovered there was at least one other part number used in between the 681-h and 1116065 and that was 1116046. If with the addition of these numbers you can't find one, PM me and I might have one in the basement.

Terrill Machine in Deleon TX did mine (from the LaSalle) and they did it well. They will be doing my fuel pump next week when I get it out of the Buick. They do not have a website, so google for their phone number.
