La pieza llegó a tiempo y es el reemplazo correcto para camioneta GMC 1977 con Booster. El producto es AC Delco original pero fabricado en china. Lo devolví porque antes de que llegara encontré otro en una refaccionaría local a mejor precio y fabricado en México, así que devolví el de Amazon sin instarlo, usarlo o probarlo, así que no puedo opinar de su funcionamiento.
