Difficult to find good examples from specific periods of time and specific plants but here is what I have on a couple of other details. Using projected build dates we're looking at cars around 140xxx - 152xxx in general terms
Closest I have from around that period is from 5R07C131xxx. It shows the cubic inch, crankcase and what appears may have been the white replacement parts decals
Have a much later example with the cubic inch and crankcase decals in the exact same locations (5R07C2290xx) So it suggests some consistency.
Have pictures of unrestored cars in the general area but it seems that though unrestored the owners chose to update the decals - originals were likely in poor condition and they made the choice
Never recall seeing (nor found any pictures) a sticker on an assembly line oil breather cap - that plant and time period
Going to move the thread over to the general 64 1/2-66 part of the site
