Hi Rob,
I know how you feel I bought a lemon off of ebay, but I have decided that I'll rebuild it, I have no time scale, but I'll get it done, I buy the bits I need when I can, If your in no rush Its surprising what you can pick up cheap, I'm currently figuring out how to install disc brakes although I may end up using RR axles as I got a rolling chassis for £50, but I can't weld so will have to learn or find a Samaritian who can, nothing is impossible or unattainable just don't set a time scale, look on as a hobby because there is always something else to do even if you get it on the road, thats the charm of them, they have a temperament unlike more modern vechile's.
