Repro Trim ring vs. valve stem

Re: Repro Trim ring vs. valve stem

The 69 AIM does not have a PO2 page but the contents are listed as I said above. It calls out the extension specifically for the PO2. The extensions are made by Schrader and are about 7/8" long.

Peace. I was looking at the 1970 AIM... 1972 may also be different.

Peace right back at you. I also don't have the '72 AIM so it may be different. Your 70 AIM matched my 69.

From '72 (the only specific PO2 reference I can find is on M299 where options are listed) UPC 10 A1, Note G references optional need for a valve extension:

Thanks, Owen. I agree that the extension was used only for "options requiring same" as stated in the '72 AIM. In an effort to help clarify a little more, I've attached a copy of the wheel options form the back of the AIM's OPTION LIST. Other than the menu of tires, (BW? WSW, RWL), the only option I see listed is the PO2 wheel cover.

I hope this helps.
