The "other" car (Eunos s/c) has quite a long throttle cable - nothing special but probably about 1mtr. as it goes across the front of the
engine and picks up the throttle body on the left side.
The original supplier wants c.£100 (must be gold-plated!).
Any recommendations gratefully received.
Thanks in anticipation, Pewe10
