I recd both of these in my Dino folder.......I assume the red one is correct for 03064? Image Unavailable, Please Login Image Unavailable, Please Login
Red cover no.72/72 is correct for chassis no. 02132 and above, but the blue cover OM was printed in two editions--no. 48/71 with second edition in 1972. Your car may have come with either IMO.
the change was approx. mid 1972 (from blue to red) the blue manual came for early E-series with the red/yellow parts book see also page 343 Dino Compendium
