Upon further inspection of this bell I noticed the gearbox locating hole just did not look right.
Sure enough it had been taken to with a grinder or some other type of hand tool.
Looks like the hole had been opened up to take the large toploader/tko size bearing retainer from the t10 size..
Not good, now how to fix?
After sleeping on it and coffee in the morning I came up with an idea, why not machine the hole out to take a modern quicktime bellhousing insert?
First make a jig up to locate the bell were it should be for machining. To do this I made a fixture up using my good ford bellhousing.
Center the ford bell in the bridgeport then swap out the damaged bell.
