VIN question

[blown motor]

The thread by smash_beacham brought up a point about my car. Mine is a 74 with a rallye dash. The VIN starts JH23G4B. Does the JH indicate that it would have originally had a standard dash? I ask because rUNCHARGER stated that the 73 340 rallye dash would start with JS23

The rally dash was standard in the JS cars, at least for 70-71 and I would assume for 72-74.
However the rally dash was optional in all JH cars as well.

No matter what your VIN is, your car could have a rally dash.

The data plate on the inner left front fender will tell you whether or not your car came with a rallye dash gauge cluster.  Look for code A62 (and/or N85), if its there, your car was so equipped; if not, it was just a standard gauge cluster.

Don't have a fender tag or broadcast sheet so I guess I'll never know for sure it it came with one. But I have it and that's cool

Also I was wrong on the JS thing after 72!

You can perhaps tell by looking at the wiring harness and other dash components; the rallye instrument cluster used a different harness (wires for the tach, clock, etc). I have been told the light bar is different as well which I suspect has different placement of the lights than a standard dash. If someone did a complete swap, you will never know but most people wouldn't have swapped the harness. A standard harness is easily made to work with a rallye dash by running a few wires, so there wasn't much of an incentive to replace it with the rallye one.

I would assume that the heater control panel matched the rallye dash (assuming the car you have has a rallye instrument cluster in it now).

My original standard harness had the clock wire because you could get the optional clock on a standard dash. All I had to add when I converted was the tach wire and an oil pressure wire. Standard harnesses had a bulb socket for oil pressure, that's an easy way to tell which was originally with the car.

Good info shared by all! Thank you

I do believe that the rally light bar has 4 lights and the standard light bar has 3 lights. 

I've personally changed half a dozen wiring harness's so if a mouse got in your car over the last 40 something years your harness could have been changed in a weekend's time. unfortunately you will probably never know for sure.  But you know for sure you have rally's now.
