Relays

Eh up everyone, posted this in the speed sub forum, but thought it could get better coverage here where all models hang out.

Do we have such a thing on this website as a resource which names various parts (such as relays) and items that can be used in place of the oem?

We all like to save a few quid here and there if we can, and if a triumph indicator relay is £20 say, but one from halfords that fits a 1996 VW Golf is the same item and costs £8, well that's nearly a tank of fuel.

Any ideas folks???

Thanks everyone
