C2:67 Can someone identify these parts.

[Gerard F.]

Reorganizing my parts boxes, and found some parts in an old 70's box. Here's a pic:


I know the two nipples on the right are my original water pump and heater hose nipple for my 67 327/300. In the picture I have them preped for plating.
But the two braces on the left I don't know. Can anyone identify them. Not even sure if they are off the car, but were in any old box with all my old Corvette parts.

Also found in the box:


Could this plug wire support be off a 67 S/B. Stainless steel, has PR on the back. Maybe a 70 El Camino which I also had at the time?

Any comments appreciated.

On the plug wire support

Just pulled my ignition shielding to see if I was missing a plug wire support.
Found my original still there with two notches on each side per the the catalogs I reviewed. So the plug wire support in the picture in the previous post is from another car.

I don't know what the 2 brackets are in the first picture. I'm not even sure that they're Corvette pieces, at all. In any event, I don't recognize them.

The spark plug wire bracket is not Corvette. It's for some other non-Corvette Chevrolet application, but I don't know what.

Jerry,

The plug wire bracket is passenger side from a early 1963 corvette and chevrolet. I can't say for sure if this style is used on 1962 and earlier chevy's. I think in 1963 the part changed to the newer style with two wires on each side like your 67. Tim

I don't think it's the part used on 61-64 Corvettes (and other 61-64 passenger cars and light trucks) and once known as GM #3744405. However, that clue you provided spurred me to further research and I think I know what it is now. I think it's a GM #3864899. This part was never used on a Corvette but was used on all 65-69 Chevrolet passenger cars with 283 or 327 cid engines for the left side wire support.

The 3864899 also became the SERVICE replacement for the 3744405 when that part was discontinued in March, 1965.

Thanks for the correction Joe, it looked like the same part from Jerry's picture.

Re: C2:67 Can someone identify these parts.

Jerry, I completely dismantled my 67 BB coupe a few years back and found no brackets like those. Maybe you ought to check out your vintage lawn mower for the missing grass catcher clamps......

Joe,

Could the plug wire bracket possibly be from a 65-66 Chevelle 396 engine.
I had one of those as a replacement engine in a 70 El Camino.

I doubt it very much, but I would not absolutely rule it out. As far as I know, this style wire support is pretty much exclusively a small block sort of thing. For one thing, it's designed to fit the configuration provided on small blocks for wire supports. I've never seen similar provisions on a big block. For another thing, most big block applications use "over-the-valve cover" plug wires. Some may use 2 wires that run in a configuration similar to small blocks, but the wire support you pictured has provisions for 4 wires. I don't know of any big block that runs 4 wires like this.

You will note that the plug wire support in Jerry's picture is, basically, designed for use on the LEFT side of the engine. In other words, when the support is installed on the left side of the engine, the plug wire loom faces FORWARD, the configuration used in PRODUCTION. The GM #3864899 was designed to be used on the LEFT side of the engine with the wire loom facing forward.

The GM #3744405 used for 1961-64 Corvettes was designed for use on the RIGHT side of the engine with the loom facing forward. Even though the GM #3864889 replaced the GM #3744405 for SERVICE, if the 3864899 is used on the right side of the engine, the loom will face rearward. I guess GM must have figured that was ok for SERVICE since it really does not make a lot of difference which way the loom faces. However, if the GM #3864899 is used on a 1961-64 Corvette application, the configuration will not be correct.
