My twopence:
Door top, glazed - 6 months, started rusting from day one, but cheap and good enough.
Rubber seal door top to bottom - 6 months, one size fits nothing, but at least long enough to be cut to size. Inside dry though
Fan belt - 6 months, seems fine
Heater, top and bottom hoses - 6 months - again, one size fits nothing but long enough, doesnt look too well though. Unlike original which was at least 20 years old, when they burst I suspect its not field-repairable (OEM is, I've had to try)
Wiper blades - 6 months, bollocks in wiping, but dont rip or break. Oh, and they didnt fit initially...
Front vent seal - 6 months. As mentioned above, but mine were too big.
Rad cap - 4 months. Shuts, but I dont know if it opens. Wouldnt buy again, as I suspect it not to.
Headlight bowl - 4 months. Doesnt rust as not metal. Doing fine.
Window lock - 4 months. Doing fine.
Oil filter - 4 months. Doing fine.
Fuel cap seal - 4 months. One size fits nothing, but you bloody well cant fit it. Stays in place sometimes, sometimes not. Wouldnt spend more money on this seal tho, so good enough.
Overflow hose - 4 months. Who cares? It's cheap, it should never be in use, and if it is, it can aswell drip on the floor or rad, as long as no one stands right above it.
Brake overhaul kit - 3 months. As from paddocks. Cheap. So is the quality. expect to buy another one just to replace these parts that fail withing 3 months or are broken on delivery.
Bleed screws - 3 months. Nothing good to say here, but that they did their job for about a week.
brake pipe ends - 3 months. See bleed screws, but a bit better. They do their job, as long as you do not try to unscrew and reuse them(yes, fitted with copper grease).
Steering damper bush - 3 months. Seems fine.
Water pump - 2.5 months. looks good quality, doesnt leak or make noises. Seems fine, but gasket was broken on arrival. Fitted it anyway as had no alternative, works well.
Rocker cover gasket - 2.5 months. Dont. You have to make sure to get the sticky stuff off. And the plastic. And even then I fished some plastic(sticky) just in time from the innards of the rocker cover.
Handbrake gaiter - 2.5 months. One size... you know the rest. Cant make it fit nicely, but was a lot cheaper when I bought it than OEM, and does its job more or less.
Carb repair kit - 4 months. Fine, but some jets are wrong size/bad quality metal, the idle valve and gasket doesnt fit. Cheap, and not worth it.
Cheers,
Phil
