My '71 VC is missing the drain plug at the bottom of the spare tire well. My parts book says its gr 12.981 p/n 9815342 and used on all 70-72 VC and 70-73 wagons. My book is from '73 so I'm guessing that plug is used in the full size wagons up through '76. The hole diameter is 1", but has 2 notches in it. Here's a picture:



I can't find anything online except a generic GM body plug like this:



It is p/n 4802102.
Probably would work but If anyone has a picture of theirs and of course if someone has one to sell, please let me know.
Thanks!

 

Looked in the tire well of my 76 Custom Cruiser junker and there's no hole like that. It has a stamped dimple about 2" square, a trough to direct drainage off the window drive cable, and about a 3/16" hole in the bottom of the dimple. Weird, but the well's not rusted out so guess they thought it would work.

If it had the plug it would be yours for the asking.

 

Thanks for looking!
