Thanks for the responses.
Next question.
What are the free wheeling hubs and how do they function.
Going from an auto hub (comon jap 4x4) I thought had had blown the front diff or half shafts on my series 2a because when I spun the front prop round by hand it moved even in 4wd then on day I noticed a little nut on the hub I turned it with a spanner and 4wd worked. How silly I felt but its easy to do I could have gon to the lengths of removing the half shafts and everything.
lol i hate free wheel hubs more problems than they are worth, i have them and if i had some standard drive flanges i would fit them, in an instant
