source for 67 oval rubber plugs
« on: May 30, 2017, 06:23:42 PM »
I've looked through my NPD catalog as well as the AMK site for oval rubber plugs like shown smack dab in the middle of the attached picture I ripped from one of Marty's posts, but can't find a source.

This is one of those things that I might just be glossing over.  Help?  Thanks, John

No one makes that one as far as I know. You have to get them off of junk cars. If there is a easier way I would like to hear about it.They are very hard to find when you need one. It is missing 99 % of the time on restored cars I judge.

Bob, thanks for the confirmation of what I've found.  My next junkyard trip I'll grab a handful or two...or three.

John,
I cannot find documentation for that plug. Can you measure the width and height. From that a part number may be determined.

It looks like the same style plug used on a 65-66 on the inner part of the front frame rails where they turn up from the floor pan.

Same style but think the size is possibly different

It is a different size. I have not found the same size and shape plug on other years 65-70. :'(

So far all I see here is "it's different". Will someone take the time and measure the hole. There may be alternatives.

Jim, I've got the measurements done, just need a little more time to make it presentable. John

OK I put together the attached PDF since there are quite a few items going on here.  A synopsis for those that don't want the gory details of the attached file.

1. There are two sizes of oval holes that were potentially plugged - a quantity of four on the radiator front apron, and a quantity of two on the inner frame rails near the idler arm and steering gear box.

2. For the front apron, there appears to be a running change at all three assembly plants from oval holes to square holes.

3. I did a quick survey of some unrestored cars, and there are some reasonable conclusions to make, although more examples would be nice to have to pin things down a bit more.  I have more data myself that that will take time that I don't have for the next week or two.

Of course I'm still looking for sources of both size plugs.  As Bob mentioned donor cars, eBay, and the like are probably the only way around this.

Also I did not have time to look in the assembly manuals, but with the attached pictures and dimensions that should be a relatively easy search.  But the better half is dragging me out shopping.  Yeah, I know.

Yes the  oval verses square holes was a running change in 67.  Square holes being the later version that carried into 68 production. Believe used for the mounting of the Cougar front end parts

I pulled both of my rubber plugs off of my Jan 31, 1967 Dearborn Conv today. Both had the number "377841-S" on what I'll call the "top" of the oval, and "SI" on the bottom of the oval. On the left on one was the number "31", and on the other, "132". I am assuming that the 377841-S number is an Engineering Number as opposed to a Part Number as I didn't find it in either my 1965 nor my 1969  Standard and Utility Parts Catalogs. John noted that he had the dimensions and would Post them soon.

I've attached a picture of each of my plugs.

+1 ;)

Guess we need to figure out what the round plug that was used for the square holes while we're at it.

Also it appears that the direction of installation was a plant thing like many other details. So far San Jose are all installed from the engine side of the radiator support while Dearborn cars are installed from the front of the car towards the engine. Could only find one example from 67 NJ and they were installed like what I found on dozens of 67 Dearborn examples
