EFE Fuel tank and other bits

[spondonchris]

Just started taking bits off the tatty efe I bought a while back to do up and found the tank is leaking. It looks a bit rusty inside too, so may replace rather than repair if I can get a cheap enough non leaking tank. Anyone got one? does not matter about paint.
Will also need a fuel cap and seat lock on the same key as neither work on the key with the bike.
Possibly s front disk too as one is very loose on the rivets
On the plus side, discovered it had dyna coils under the tank
