Bending plastic:

Shaping the back, and attatching the bottom:

quick teaser:

Ive still got to permanantly mount the projectors, and then figure out how to mount the BMW projectors. Then Ill have to make a cover plate like dion and amarv have done.
If any of you veteran retrofiters see something that needs to be adressed PLEASE let me know, either here or in PMs!
