And technically i could stil change it but i would have to change everything. Plus you need to keep the Bosch reflectors which are nothing close to the stock ones. I think it owuld be extremely difficult to use the stock lens with the bosch reflector. Unless someone has already completed it and there are pics somewhere,
I have spoken with Z-ster and he mentioned the same thing yet he used the bosch lens like me and said the only difference is the cutoff will be even sharper but if you look at his pics he has posted on aus300zx.com they look pretty sharp to me.
