yo,
As jpscott713 advised; Air Cleaner Bracket (9B672)
If you're not a yard hunter;
Autolite 1100 Air Cleaner BracketStarting at: $19.99
"...This very obscure item is often damaged on Autolite 1100 carburetors. Now for the first time, it's available through Champion Mustang. We had this part made for our own carburetor rebuilds. We're not currently offering this part to any other companies. This is another Champion Mustang exclusive part.
This item is very light and we can ship it out via USPS Priority Mail at a lower rate than the website can calculate. Look below at "Related Items" and add in "USPS Priority Mail" to your shopping cart. This only applies to small carburetor parts as the box is limited to the size of a VHS tape. Select "Freight Shipping" checkout only if you have added in the "USPS Priority Mail" option to your shopping cart..."

"...We have almost anything to rebuild carburetors, including kits, diaphragms, jets, rods, choke parts, accelerator pump and power valve covers, solenoids and dashpots. On many of these parts, we are the ONLY source. We make many parts ourselves using our CNC plasma cutter. Ask us about the availability of any part you need. We do have a $20.00 parts minimum order. Please refer to our
carburetor diagrams page for ease in ordering. All parts return are subject to a 30% restocking fee..."
