Speedo inner cable.

[pooch]

Bought a mail order repo inner cable ..says vintique A-17262-A 28 -30 with oval speedo.

My car is june 28.

Problem is the cable that came out of is .125 inch diameter and is squared same on both ends.

This repo cable is a square on speedo end and a key on gearbox end and is .145 diameter.

The gearbox drive has the small square hole. so do I have some bodgy drive fitted?

And IF I had the correct drive, how does a repo inner fit the case with 2 large ends on?
