Hi all, bought a crystal gear package off eBay and made sure from the seller that this is compatible with the F chassis 4 series. and was wondering advice on how to fit it in? Seen a video on how to do it but seems very technical - alternative - is there any company based in London that I can ask to get it fitted in?

I’m also worried about the parking button being on the bottom rather than the top. Didn’t wanna return it as I did like the crystal interior. Any advice helps!
