I just watched the Spaghetti Eastern Way of the Dragon again. It was an extra trailer on the disc that jogged my memory about another Indy reference:
Jackie Chan's Armour of God. A film that has may only have been mentioned here twice. I remember thinking of Indy the first time I saw it on TV.
In the trailer itself Jackie's moving behind a rolling drum for cover à la Indy and the gong in TOD.
There was more, besides the treasure hunt itself, but it's been so many years since I saw it in full.
