I have for sale a dozen A-series Weber adapters. They will adapt the stock intake manifold to a Weber 32/36, 28/32, 26/28, or most other DGV style downdraft carburetors. I'm asking US$5.00 each plus shipping. If interested in one or more, send me an e-mail to dimlight65@aol.com. There is a picture in the photo section.

how do you ship stuff like that

I hadn't given it much thought. Since they are about the size of an audio cassette tape, I thought I'd use one of those padded envelopes with the bubble wrap bonded to the inside. As for carrier, I'd get prices from several sources (UPS, FedEx, US Postal Service, etc.) and let the buyer choose how much he/she wants to pay for it based on how quickly they wanted it.
Okay, so I have given it a bit of thought.

Just an update. I have had a closer look at the adapters. Turns out two of them will not fit an A-12 manifold. I have removed them from the pile. I have also sold four of the total leaving me with six. Let me know if you need one, dimlight65@aol.com.
