A northern character once visited the south to run in the long distance series with his Commodore. The series in those days was restricted to cars complying with the South Island production race series regulations.
We were at Teretonga and he withdrew after testing because of gearbox failure, keen to see him compete we offered a loan of our spare one but he declined saying that his driveshaft would not fit it, not a problem, we offered our spare driveshaft and he countered with the info that our gearbox would not fit his clutch so we offered our spare unit and the counter was that this would not fit his flywheel so I went and had a wee look and had to report to our team that he was correct for none of our stuff would fit on the back of a NASCAR engine.
