The Official "What The Heck Is This?" Thread

Maybe a valve cover bolt with a extended pin for a spark plug cable holder.

 

I may have just found the answer to my own question. The double-ended stud looks very similar - though not identical - to this "GM Engine Mount Stud Bolt Flange Double Head":

What size is it? 1/4"? 5/16"? 3/8"?

 

The smaller end is threaded 5/16-18, and the larger end is 3/8-16. Overall length is approx 2-5/16".

Note the traces of "Buick Green" on the captive washer, which leads me to believe it had to have come off of my Dauntless, possibly during a rebuild about 9 years ago.

 

Only nine years ago, and you don't remember it??

 

At 62, I’m often wondering what I used to know that I can’t remember forgetting….

 

At 66, amen brother. Ron

 

I’ve been redoing the frame on my ‘71. There are two plates on either side of the inside frame rails at the transmission mount. On my frame both were very rusted and falling apart.
it seems I’ve read threads about these before, but I can’t find a thread any way I search.
What are these called and are they necessary to replace?

 

I would replace them, they spread the load of the transmission on the frame. I've never seen a replacement, it's just holy flat stock.

I'ld call them straps. Or sandwich plates.

 

Thank you Jw60, that makes a lot of sense.
I’ll make some replacements before bolting in the transmission mount.

 

If you don’t have bolts left over you did it wrong….lol

 

When I have a younger guy start I have been known to say I have most likely forgotten more than you have learned. And some day I wonder why I get up from my office chair, only to sit back down and remember…I think there is a limit pressure switch in my backside that only engages my brain when I am sitting down. Lol

 

I have the head off my 1965 CJ5a, to repair a stuck exaust valve that I broke trying to unstuck it, and I see this brass fitting that isn't hooked up to anything and now want to know "what the heck is that"?

 

I removed the fitting to find why there wasn't oil shooting out. It looks like someone ran a small screw into the 1/8" tube and it's broken off in there. There's no added oil guage on the dash. Weird. I'll be sure to put the proper sensor in there. Thanks for the help!

 

Found in my box of parts...I get the 4.89 gearing I guess but where would this be mounted?

Thanks

 

On the axle cover adjoining bolts.

 

Front or rear? Rear I surmise or was there supposed to be 2, or is the assumption one and the same.
