Ok I will be attempting to install some of the Mini D2s projectors into my stock housings hopefully this weekend! I know there are multiple threads addressing many different things about the procedure. However, all of the "how to" threads say to remove the back of the housing (black plastic portion) along with the adjustment screws. My question is why is it necessary to remove? I understand removing them if you are using the FX-R projectors that require cutting the housings, but just don't understand why it is necessary to remove them using the mini kit which does not require any cutting of the housings. Any advice would be greatly appreciated!! Just trying to keep everything as simple as possible and not do anything that is not actually necessary.
