something doesn't look quite right.....there should be some sort of mounting
point on the rack for the bars or sliders or whatever was used.

also......the arms at the top of the strut nearest the frame are close together,
while the center strut arms are even with the sides of the platform/top.

i'm thinking normally....struts are at the outer edges of the rack platform
except for the end struts away from the bike frame. not sure if that is
functional or just aesthetics.

and where is the lip/bend upwards that blackburn usually puts on the end
of the rack nearest the frame?

can you provide a photo of the other end of the rack?

sure looks like you might have a front rack mounted backwards.
