Alternator Brace ID

[Loren L.]

Alternator brace is about 16" overall length, with approximately 6" overall bending right and curling over the alternator, with about a 4 1/2" long slot
for the actual attachment to the alternator; brace is also stamped "GT".
The above =s ___________?

Loren,

How about a photo of the brace next to a yardstick? I have about 50 to 60 Chevrolet & Corvette generator & alternator braces in my 30+ year collection. Many are very similar in shape and size but obviously are different. The word "about" is much too vague.
I even have a few with a "GT" stamping.

If I had a scanner, the picture would already be there.

Loren,

Actually a digital camera would be better. Since I am in the 21st century I will dig out my braces stamped "GT", take a photo, and post it on this thread.

As you are likely aware, GM used a lot of different alternator braces for all sorts of different applications. I can't recall a single one that ever had a part number on it although there may have been a few that did. This is another case of parts that should always have had a part number embossed on them for identification purposes, but GM never required it.

Re: Alternator Brace ID

Joe,

I have studied alternator & generator braces for about 25 years and have over 50 in my collection including several NOS braces. I have identified most of them but there are still about a dozen of them which are still unidentified.

I can only recall one brace that I removed from a 58 Chevrolet 283 (also used on 55-57 Corvettes) that has a stamped GM part number "3704884".

I have 3 identical braces with a "GT" stamping which I believe to have Chevrolet truck application. The other brace stamped "GT" is the front brace from a 1968 Camaro Z28. I assume "GT" was the manufacturer.

I have had several original and one NOS 63 Corvette brace all stamped "V". I also have a NOS brace stamped "V" with a GM tag # 3868882 for a 65 Corvette (P/S w/SHP 327 exc. AC) that I have been trying to sell for many years but apparently this is not a common option combination. The 3868882 brace is almost identical to the 63 brace (GM # 3825462) except that it is about 1" longer.

I have 8 64-65 Corvette 327 braces, 6 of them are stamped "B", the other 2 have no stamping.

It is unfortunate that GM did not stamp all their braces with a part number.

Re: Alternator Brace ID

Loren,

I found the alternator brace pictured below in the 2 photos on the left (with "GT" stamping) from a 1968 Chevrolet truck. The length of the slot measures 4 5/16" long. The straight portion is 7/8" wide and 1 1/4" wide at the bend. I have 2 more of this brace that I bought at swap meets for $1 each.

I must have sold my 68 Z28 front brace stamped "GT" but below (on the right) is a photo of a photo (from a book) of the front & rear braces used on a 68 Z28.

I expect that the manufacturer denoted by the "GT" stamping probably manufactured a lot of different alternator braces for GM. If so, there's no way that the "GT" stamping could be used to identify the part number or application of any particular brace so-stamped.

Joe,
As I stated in a previous post the "GT" stamping is the manufacturer. The 68 Z28 front brace that I sold also had a "GT" stamping just like the 3 Chevy truck braces that I still have.

Something I find interesting is that the drawings for the VAST majority of GM parts specify that the "manufacturer's ID must appear on the part" and that "omission requires approval". Yet, many GM parts have no manufacturer's ID. It's hard to understand why any manufacturer would go to the bother of seeking GM approval for omitting the manufacturer's ID and even less likely that GM would approve such a request given the emphasis placed on such markings in the drawing.

So, how all these parts without manufacturer's ID got out there I have no idea.
