67 and 69 Barracuda back-up light

I love doing this stuff.

It's like a puzzle that I can finish.

I take photos and some dimensions.

And figure out what the original designer back in 1967 was thinking.

Did he use numbers like 1.1 or 1 1/8 most of the time I'm finding that the OE designers would use decimal numbers and keep to the whole decimal. 0.1, 0.2 etc. Some times 0.15 or 0.25

Then the angles, if I have the real thing in front of me I can measure the angle, many times I use an educated guess. I figure the designer wanted to keep the machinist from beating him up so he chose easy angles, 30, 45, 60 etc. maybe 10 or 15 if it was really needed.

Curves, mostly circles with the occasional ellipse.

Sometimes a spline had to be used, due to weird geometry.

It's really rewarding when I draw it up and print it and it comes out good, then a bit of refinement, and I have a finished product.


The latest print. Moved some holes and got the base the correct way around.

Next will be the changes to the cone to help with the closeness to the bulb.
