Thanks for the information - I'll be honest I haven't looked closely but
can imagine what you mean although another poster mentioned about the
speed and I seem to remember alternators having smaller drive pulleys? I
guess on the need front I'd probably not push it too much but I did fit
Hella halogen replacement headlamps, a pair of Cibie Oscar+ and a small
electric winch to the land rover when it was last on the road 20+ years
ago and have found the battery takes a bit to recover to as I was going
to spend some time fettling I thought I'd do some mods at the same time.
But it does start a treat on the handle so I could always fall back on
