RE car weights and code numbers.

I looked in the index for the weights but my 2 74 novas both start with the same 6 figures.---1X27H4 . I don't see any figures like these for a two door coupe. All the figures on the site for weight begin with 1XX27 or 1XY27. Can anyone explain this to me. I have had a hell of a time trying to find out what these two cars came with. I found that they were both made in Van Nuys CA
but thats about all I could find out because I can't match my numbers to any of the stuff I find on the internet. Please don't tell me if you think I really don't have Nova's. I don't think I could take that today.:eek: ;)
Thanks
Lance

X in the VIN is the same as XX on the body tag and means a standard Nova.
Y in the VIN is the same as XY on the body tag and means a Nova Custom.
