if i remember correctly when you take the instrument panel out you can reomve almost all the bulbs without taking anything apart, and those LEDs you have pictured are designed to fit in the holes perfectly.
but be warned they look crap, very dim and the light doesnt spread so you end up with a few circles of brightish light and not much else. plus the bravo/a is back lit so it suffers even more from the dim light.
i've got a box in my garage with many LEDs exactly like that, even ones that change colour, i used to sell them to local kids and fit them for a few quid extra, but i stopped doing it because people were less than satisfied with the amount and spread of light. they dont do what they say on the tin. bulbs are needed to get enough light, LEDs just arent bright enough and the light is too directional, whereas a bulb spreads light out evenly in all directions.
i wouldnt waste your time with them
