Large CNC-machined billet aluminum adapter/bellhousing plate for an engine-to-transmission swap. Here's what's visible: - **Large round bore** center opening (~10–11" diameter estimate) for transmission input snout - **Rounded-square outer profile** with multiple bolt holes on all four sides — typical of a swap adapter mating two different bolt patterns - **Machined face** on both sides, still has machining marks, no anodizing — raw billet - **Visible small tapped holes** around the inner bore lip — likely for a pilot bearing retainer or seal - **One sensor/switch port** visible at top of bore opening (possibly neutral safety or speed sensor bung) - No brand markings visible; appears to be a custom or small-batch CNC piece - Condition: light handling marks and machining swirl, no cracks or damage visible Shipping note: Heavy piece (~8–15 lbs estimate), recommend freight quote or flat-rate box. Verify bolt pattern match before purchasing — bring a gasket or measure your housings.
