The choice of drive size will depend a bit on your vehicle - i.e. how many rusty bolts you expect to need to twist off. 3/8" is easier for the small body bolts, but for some of the mechanicals you are probably better off using 1/2", including things such as head bolts, tie rod ends, shackle bolts, which probably need a torque wrench with 1/2" drive. I have both, but if keeping it to one, you probably should go 1/2".
Most of the hexagons on the vehicle should be AF, and I can't think of of anything smaller than 7/16 or larger than 1" (what size are the nuts on the end of the axle - they may be 1 1/16"?) except for the wheel bearing nuts, which are 2 1/16".
There are still a significant number of Whitworth/BSF hexagons including wheel nuts, drive flange bolts, and a varying number of others, depending on the age of some of the parts; don't forget that in the last 44years it may well have parts fitted that have been taken from Landrovers back to 1948! Sizes from 1/4"BSF/5/16W to about 9/16"BSF/5/8"W
There are a few hexagons that are BA sizes, one that comes to mind is the lock screw on the Zenith choke lever, but there are others.
There should not be any metric sizes, but it will almost certainly have some - for example, most tierod ends sold today have metric nuts on them, and any number of body bolts may have been replaced with metric ones.
I find that I mostly use sockets and a set of AF ratchet ring spanners.
Hope this helps,
John
