Your build is looking great
Looks like you are making some steady progress
Here's a clutch cable that many of us are using ( Myself included ) .... Good price too
Capri Clutch cable
Nice and short, does the job a treat.
Not too sure about the throttle cable .... Not got that far yet
I guess once I am ready for that, i'll pop down the motor factors & buy one of those universal type cables then make it up to suit the car.
Flexi Pipes.
Again not got to this stage yet .... When I am ready i'll work out wich way I want to route them, measure up & get some to suit.
If you post a picture of your engine & radiator in situ, I am sure that someone will be good enough to knock up a drawing of the coolant hose layout for you
Well done on your progress.
