TODO Fixes - Creaks, Bangs and Rattles

KGA is a nice car to drive, but a touch noisy. There are four origins of the creaks, bangs and rattles which we need to fix:

• exhaust - a stainless exhaust from P. D. Gough was fitted some years ago, and very good it is too. Seems a slightly different fit though, so the exhaust bangs against the rear bumper over potholes, sleeping policemen etc.;
• horn ring - annoyingly rattly and the horn itself is difficult to engage. Bits of old mousemat used as padding is apparently the answer;
• gearbox mounting - or somewhere similar, there's a creak on acceleration suggesting a loose nut or two;
• seats - both passenger and driver seat need tightening.

Judicious use of spanners, hammers and WD40 should sortall this. Although it's been easy enough to live with so far...
