Thanks guys, twin header tanks sounds like a good idea in which case. Going to try it with the plastic stuff for now, it's cheap enough to at least try.

Also need to get an MOT, so need to sort a handbrake. Planning on using something like Mondeo rear calipers as they have a built in mech for handbrake.

Chip - what did you use and any other issues with the MOT I should consider?

Thanks again
