Just an fyi the judging standards shows the 2 different worm rearend housings. The later worms had a hump on the worm gear area, inside is an angled channel that catches the slung oil and runs it back to the rear thrust bearing directly. Clearly lubing that bearing was an issue otherwise ford would not bother changing such a large casting late 29.
