I have a 1997 E-250 currently with sealed beam headlights. I would like to change them to composite headlights.
Do I only need to change the headlights? the grill?
And can I mount the composite headlights to the existing big black mounting panel (that spans from headlight to headlight)?

Upon examination of my current black mounting panel, it doesn't look like I can just mount the composites on since some tabs seem to be missing. Is there another part that I need to make them able to mount?

Any part number would be appreciated also.

Thanks in advance.
