I need a precision-modeled headlight moulding for my 1977 Year One Trans Am that will let me swap the stock sealed beams for a pair of modern aftermarket units. The frame has to match the factory opening exactly while adding new tabs, bosses, or brackets that line up with the lights I’ll be using. I can supply high-resolution photos plus both the outer assembly dimensions and the original mounting-point measurements, so you will have everything required to recreate the geometry faithfully. I’m flexible on software—whether you prefer Fusion 360, SolidWorks, Blender, FreeCAD, or another professional CAD package, use the tool that lets you work fastest and most accurately. What matters is that the final model is watertight, dimensionally correct, and delivered in STEP (for machining) and STL (for 3-D printing) formats. Deliverables • Parametric CAD model of the moulding/frame • STEP and STL exports ready for CNC or FDM/SLA printing • A brief drawing or PDF with critical dimensions and mounting-hole callouts • Up to two minor revisions after a first test print to dial in fitment Acceptance criteria • Fits the OEM opening without gaps once printed in scale PLA for test fitting • Mounting holes align within ±0.5 mm of the provided measurements • Holds the specified aftermarket headlights square and at the correct depth If this sounds like your kind of project, let’s talk through any questions you have about the measurements or the lights themselves so you can get started right away.
