Craig, I have seen somewhere - don't know if it was here or elsewhere, that an italian Morgan specialist does a badge bar specifically for mounting spot/fog lights. Be buggered if I can find it now though.
I think a set of 'period' looking spots would look great on the front of my 4/4 but share your reservations about drilling into the bodywork.
Try the Italian dealer, Borgi for a spot lamp solution.
I just saw this. The photos that I took just after I had the Borghi badge bar and driving lights fitted are
in this thread. The bar is anchored to the overiders and the cabling is hidden behind the overiders.
I'll Post them here anyway.



PS. There is also a thread on the same subject
here.
