.. or the Porsche clevis parts to mount on the cable (nope can't find them or anything similar online anywhere).

Anyone got either at a reasonable price please..

If I remember right I used a beetle hand brake outer sleeve, filed the metal elbow part with flats to fit into the Porsche backing plate and then used a bay window clutch cable the wrong way around which had the correct end to mate with the Porsche brake shoe lever. I then marked the length and had beetle threaded ends fitted by speedy cables.

As Chad said but beetle outers and 2 second hand long side 944 inners from a Porsche breakers with beetle adjusters crimped on.
They came with the clevis pins already filed.

Sorry,
Should read:
Already fitted.
If he is still about he trades under
Mikes Porsche parts or something similar, I'll try to dig out his number as most breakers would only sell the cables in mismatched pairs.
