Question on lower Alternator brace for 63

[Edward J.]

The 63/64 judging manual states the lower brace(bracket) is spot welded. not stitch welded, is this correct? All the one's I have seen are stitch welded.

Hi Edward,
Funny, I just read this very same thing in the judging guide last night because I had sandblasted and painted mine. I'm in the same boat as you. Mine is stitch welded twice on both sides each about 3/4" long. I wonder if that's what they meant in that it isn't stitch welded down the whole seam?
Aloha,
Irby

Irby, I am thinking its a era in the manual. mine is exactly as yours. it has two stitch welds on each side. How about some of you other 63 guys take a look at your brackets?? It maybe the same on 64's??

The welds are as you both describe.
Either the guy in charge doesn't know welding terms or he has another error in his manual.
How about you letting the 63-64 TL know you've found another error??

Enclosed are 3 photos of an original (re-painted) 3825460 63-E64 Alternator bracket (without AC). It looks like spot welds to me.

Years ago I had a NOS L64-65 Alternator bracket, GM # 3860461, that had "stitch welds" along the top and bottom. The difference is the location of the 1/4" treaded hole (as shown in my drawing) and probably the types of welds. I also had a few used 3860461 L64-65 brackets but I don't remember how they were welded.

The bracket on my 63 looks like the photos David posted. Spot welded not stitch welded.

The original bracket on my '63 is spot welded.

My later '64-'65 bracket is spot welded. Just like Dave's.
Nice pics and drawing Dave. Thanks very much.

Those '63 and early '64 brackets are hard to find. Outside of the threaded hole the brackets appear to be identical.
What is the logo on the threaded bolt that holds the heater hoses to the bracket via the clamp/bracket?
As I recall it could be no logo or??? Forgot. Is it a self starting thread? JD

You might want to look up the definition of SPOT WELD and resistance welding.

Very nice Jorjorian. Thanks for sending me the email on spot weld.

Re: Question on lower Alternater brace for 63

Bob J., I think your thinking as I am, a spot weld is different than say a tack weld, but I guess technically speaking it is a spot weld I guess.

Re: Question on lower Alternater brace for 63

So then our '63 brackets are in fact not spot welded. Interesting. Either is the '64-65. Not spot welded.
Anyhow this why I don' get anything done in the shop. But this is more fun. Later, JD

Here is mine on a Mar64 car. Note two holes! Perhaps it was during the transition period? Can only say it's the original as of
Aug 67. Original owner told me that the push rods had been replaced at one time, removed head? do not know but will ask when I see him at Nationals.

Alan, my March 19th car has the two holes, forward one isn't tapped. FWIW.
