1970 Camaro hidden partial VINs

[CamarosRus]

I'm asking that this thread be revisited......

Once Again, another thread with NO conclusion

Needing to know (if possible)

1) Where the 2nd Gen sub frames WERE built ?

2) WHAT letters they were coded with ?

3) Did Norwood ONLY use frames from XYZ and Los Angelses only use frames from ABC.......or was it Frames from all mfg went to both Nor and Van Nuys ???

Another resto point we'll probably never know answer too....somebody other than me needs to do spreadsheet with car build date & location versus subframe date and letter code........

Oh well !!!!!!
