You read way too much into my response, I could care less what you do with your car. In fact I've never even noticed your name before, had to look to see if your a new member.
I wanted you to see what a reflective stripe does in the light.
Also was just pointing out what I and others will notice when we walk up to a car on the street or at a show.
My second response was because you asked a question about the bumpers on my old car, no more or less.
Carry on with your plan without a worry about me.

If you need any other, let me know.

I just measured mine. My numbers are slightly different than what I see above, I don't know why. My car is prob 95% all original factory.

The roof segments are 8" by 3.25". The side strips have the same overall height (3.25") and edge length (8"). The distance between each segment is 1/2".

Pics attached.
