Factory Correct Restoration Details

[mygmctruck1]

I have been reading this and though I am not doing mine any where near factory correct , I have noticed some things that are not factory correct for my year truck.
One is the arm rest , mine actualy came with 67 arm rests , it’s a 68 truck ( GMC )
I also have a 69 mustang , I converted to electronic ignition and of course needed to find that infamise pink wire ? I could never find it , what I found was a red and green wire in it# place and it came that way from the factory.
I worked at Lansing mich Olds plant and I know before that line got shut down for parts shortage , they would use what they could . Shutting down a line meant money and that wasn’t going to happen. So you never know what kind of things they did to keep the line moving.

I looked through this thread to get some restoration details. There were a couple of references to the both the Flint and Tonawanda engine plants. To help those that come to the thread, do not forget that these trucks may have engines built in other plants. My engine, for example, was built at the St Catherines plant.

If yours is the same and you are having trouble finding cast dates, check the passenger side of the block below the cylinder head. Hard to see if exhaust manifolds are in place and the numbers are upside down.
