  1. Thanks, Pete I'll treat her to a new set of HT leads - I'm surprised she was running at all with such high resistance caps! Paul
  2. I have just noticed that my 1969 Herald 13/60 is fitted with 10000 ohm resistor plug lead caps, I'm not sure if this is right, it seems too high ? Should it have resistor caps at all, and if so what should be the correct rating? She is fitted with non-resistor NGK BP6ES spark plugs, and standard points, condenser & coil. (some misfiring under load when cold has been experienced) Any comments, or suggestions please. Thanks Paul Ballamy
  3. Hi Lawrence, I fitted a T9 gearbox to my 1969 Herald 1360 Convertible last winter. As it is mechanically very similar to the Mk 3 spitfire I hope you will find this information useful. Regarding the gear lever position, I did not modify the gearbox remote housing, but chose to shorten the handbrake lever by 1.5 inches. Flywheel/clutch Firstly, I fitted a modified crankshaft spigot bush, as the T9 has a larger spigot diameter. A Spitfire 1500 flywheel was fitted (with bolt adaptors) to accept the larger Ford 23 spline centre plate (Sierra 1.6), a Spitfire 1500 pressure plate was used. (no adverse effects on engine pick-up/smoothness) Chassis/tunnel I had to cut away small sections of the flanges on the main chassis legs to allow the gearbox some clearance. The tunnel had to be cut back by a couple of inches - although this may be different on a Spitfire? I had to modify the gearbox tunnel, although you can get T9 tunnels now. Modified tunnel carpet section will be needed. A Cortina Mk 2 gearbox mount was used - fitted below the flange on the chassis leg to give enough clearance. Gearbox I used an adaptor plate, and modified bellhousing centre sleeve. There is some drilling & grinding of the gearbox casing, and bellhousing required, to reduce this I used Allen headed machine bolts ( a more compact bolt head) to secure the bell housing to the gear box. Also some shortening of the input shaft may be required. Prop-shaft A new bespoke prop-shaft and speedo cable were fitted. Please note that every installation is slightly different, and each owners level of mechanical skill/experience will differ. My conversion took all winter with a fair bit of trial & error, I think the box came out 3 times to get things right ! The end result was a transformed car with a quiet & much stronger transmission, plus the benefit of a 5th gear which drops the revs by about 22%. She will return 45mpg and cruise at 60mph at about 3000rpm.
