I purchased the 69-70 Scott Drake concours antenna. I haven't installed it yet but I thought I would provide initial observations as compared to the Marcus Anghels V1.1 OEM antenna guide. My opinion is as follows. The design of the antenna seems to be an accurate representation of the OEM antenna. The OEM design features without a measurement comparison seem to good. The cover material is incorrectly made from stainless steel. The crimped metal retainers on the two cable attachment assemblies are made from stainless steel. I think the original clips were zinc plated steel. The four screws are 1 inch in length and made of stainless steel. The OEM screws were 1/2 inch long and had S36 plating. All product markings are not present. In my opinion this is not concours but a decent repop. Improvements could be as follows; The correct screws are available at home depot. The cover could be chrome plated. I hope this is helpful for someone that cant find a good OEM antenna. It's way better than what I current have, so hopefully it installs ok. Alan
