Engine bay looks already very nice, what kind of clutch cable are you using and where did you get it from.
if i compare the length of my mk1 o2a clutch cable from htt and yours.
there a big difference in length, yours is longer.
and is the end connected to the gearbox bracket at the end facing towards the rearend of the car.
i also notice that you cut and rewelded the up and down moving lever.
to aling the bended stainless arm with the balljoint connected to the above mentoined lever.
