Here's an issue I came across with the Time Expander Assembly. The NEW reproduction cam has a BIG problem (one on the left). Let's see if anyone picks it up.. 

Looks like it might have 2 issues. The hole in the centre for the shaft doesn't appear to have the flat spot. The disc itself also looks to be of a slightly smaller diameter, at least the distance from the centre to the 9 o'clock position looks to be less on the reproduction.
