The gearbox will be what we call a 240z/260z B box downunder. The 280z B box has a wider 2 to 3 than the 240z/260z B box. Most Z in this part of the world have the 240z/260z B box only the 280zx had the wider 5 speeds. They are a good gear box to have as they are quite close ratio with only a wide 1st to 2nd. My 260z has one of these.
re the cam cover yep most L series have those. The rare ones are the same down here also. ie 2400 o.h.c (on the series I 240z), I believe there were also 2000 o.h.c for the very early L20a (twin 40mm SU carbs not like the 240z 48mm SU). Only the very late L28 83-87 (yep the JDM keep using the L series until the R31 skylines when the RB relaced the L series) had the very chunk NISSAN cam covers.
Most of the RHD dash crack. Here in NZ I had my covered/restored. Other than that I am sure I could see if I can find one for you?
