hey everyone, im trying to find out an approximate build date of my HK GTS 307 Monaro, it is a Sydney built car has a firewall number of 307**SS, any help would be appreciated

If it has a firewall number of 307**SS then it is dodgy.

I think you'll find people here very helpful, and what they are trying to say, if somewhat tactlessly, is that you'll need to provide more information, and that the SS suffix doesn't seem to follow the norm. Not impossible that it is correct, but unusual.

Thanks Byron. I respectfully withdraw.

That makes far more sense and is far less confusing! I can tell you HK23xxxSS are June-July 1968 so HK307xxSS being 7000-8000 cars later is more than likely in the July-August region. Unfortunately chassis numbers on these aren't an exact science as the Pagewood numbers were put on straight after paint so were done in the body plant, meaning if the car was delayed for whatever reason (which many V8 HK Monaros and GTS's were) then it can get out of whack a little with its final completion date. However the PSN (end part of the VIN) gives you a far better indication as it was allocated and put on near to the end of the assembly plant at Pagewood at this time.

Steering box helps a bit, as does column. Will get you close to the mark.

thankyou HK1837, the Pagewood background was interesting,

I was told that the early HK bodies or that some of them came through the Pagewood plant with the "A" pillars having a slight ridge in them that was different from all other HK bodies,

do you know if there is any truth to that?

I do not for the life of me know why people think that the full chassis number is such a secretive thing. It is the number that the car is registered by and nothing else. No two cars can have the exact same chassis number so putting it up here or anywhere else makes no diference. infact if your car is registered and has a rego lable this is the number that would be on the label. For ALL the world to see.

if it was such a secretive number then they would never put it on display on the rego label.

Later models have the equiv. number displayed in an opening in the front windscreen.

The "hysteria" around these numbers is generated by people who FA about Holden numbering systems and make false statements, scaring peope into thinking they are going to loose their car if someone knows its identity. The chassis numbers does not tell you what the car was only that it was a HK built in Sydney, so if you wanted to not let peolple know it was something specialou could have said I have a Premier with chassis number HK30712SS, can anyone date this chassis number and we would be no wiser that you owned a Monaro.

My First HK GTS was HK28113SS and was a very early August 68, being regoed 19/8 and having the body plate located on cowel panel instead of firewall. It also had no boot or glovebox light and latter pillars.

thanks for the help guys, it looks like she's just a little older then me, which is all I was wanting to find out,

I understand that putting my numbers up on display will do no harm to my car and only an idiot would use the same number as one already out there,

what I am thinking is that if I put my number up here on the forum and we talk about its build date etc, someone who might be fudging a Monaro with a body number that is close to it, either on a shell already or purchased with some tags on an auction site, then reading this forum he would be getting the heads up on what dates to look for to build the car from other parts/cars and could sell it off as something its not to someone non the wise,

only trying to eliminate the possibility

and thanks to everyone who replied
