70 L-78/TH400 Camaro?

[CamarosRus]

As one of the owners of a survivor 1970 L-78 Camaro (M-21/4:10 12 Bolt) I have been very interested in the above thread. I would think that one of the best ways to determine a factory L-78 Automatic would be the lack of a 4 speed transmission shifter "hump" in the tunnel floor. Norwood cars didnt come with Build sheets but had L-78 on the trim tag, whereas the LA cars had build sheets with NO(L-78) trim tag markings......I just think its very unusual that with 600 1970 Camaro made, no one has any print,window sticker,build sheet,magazine articles or photo evidence of this application......Chuck Sharin
