This is a brand new, highly collectible New Old Stock (NOS) Genuine BMW 8-bolt driveshaft flex disc coupler, universally referred to as a "guibo." Manufactured in Germany by original equipment supplier Goetze, this item features the factory molded manufacturer tracking codes "38.502" and casting reference "1106113.3", which cross-references directly to official BMW part number 26111106113 (or alternative legacy record 26111106113). It is engineered natively to filter out driveline vibrations for the 1967–1976 BMW 2002, 1600, and related E10-generation manual transmission models equipped with a 4-bolt output flange.

The authentic dampener unit features structural high-shore 75 rubber webbing, heavy-duty molded metal bolt-hole inserts, and carries an embedded "Goetze" script stamp alongside a period-correct manufacturing date clock graphic. Notably, this vintage part retains its factory metal installation compression band intact around the outer perimeter. This temporary structural ring must remain clamped tightly during installation to ensure smooth bolt-hole alignment and must only be snipped free once all eight driveshaft companion flange fasteners have been torqued to spec.
