Thanks. Will try the speedo drive I have now. If that doesn't work I'll try the other option.

It's a bit tricky with the T5 box that was mounted to Cosworth engines and cars. If you look at the calculator you will see that the T5 box has usual 7-9 teeth driver. Not so the Cosworth box, it has only 6! With tyre size 245/60/15 I need 15 teeth for the speedo drive. But the Cosworth speedo drive has 21 teeth.
The problem is not new.
