How car parts actually work on Yeggi and GrabCAD
Finding parts for your car on Yeggi
Yeggi is a search index rather than a host: it does not store files, it points at listings on other platforms. For car parts that means it inherits the fitment metadata of whatever it indexed, so a search for a specific model returns whatever the source platform's title happened to say, and you finish the job on the destination site anyway. It is genuinely useful for discovering that a part exists somewhere, and genuinely unable to tell you whether it fits your generation, because that information does not exist in the pages it is indexing.
Finding parts for your car on GrabCAD
GrabCAD is an engineering CAD library, and its automotive content reflects that: assemblies, mechanical components and reference geometry aimed at engineers, distributed largely as CAD source formats like STEP and IGES rather than print-ready STL. The models are often more precisely specified than anything on a consumer platform. They are also frequently not printable as downloaded — wall thicknesses, tolerances and support geometry are drawn for machining or injection moulding, so using one on a home printer usually means reworking it in CAD first.
