I had an opportunity to look at the after market covers just few weeks ago.
Very disappointing. Problems are followings:
1. Chrome trim is made very poorly. The shape of the trim is very thin, wavy and bumpy. Almost look plastic. As someone mentioned already, they NEVER FIT right.
2. Plastic lense is OK, but not as good as 35 year old original ones. Besides, they do not fit an original frame. I was going to buy them just for the replacement lense's sake. Nop! They do not fit at all(length witdh, shape)
3. It does not come with hardware. Original hardware set is 5 brackets on each side on regular nose, while 6 brackets on G-Nose set up.
I have few photo of my brand new covers, brakets, and instruction.
Brackets can be made as I tried one in the picture. You buy $1.5 1 inch width bracket and drille 3 holes. Then tap the middle one.By the way, there are wood screws to hold on the brackets, and round head bolts hold the covers. Screws are cad. plates and bolts are not chrome. This optional headlight covers came out around mid 72 when they started putting metal headlight buckets. So it makes sense. If you screw directly through fiber glass ones, they will not last!
My impression is that I do not mind spending $400 for a better quality ones than wasting money for a $25 look products.
