Excellent. Glad that the pics help. There was one other pic that I forgot to talk about, but it's so simple that it probably goes without description. However, since I already took it... Here's what the main bracket looks like with the take-up reel removed. They used plastic bushings on either side of the take-up reel. Don't lose them.

Also, for those of you that are having latch mechanism issues... Can you tell by looking at the pics how the centrifugal latch is supposed to operate? If not, I can annotate one of the pics to explain what happens when you try to pull the belt "quickly" off the reel and invoke the belt latch.

Interesting. The mechanism in my neighbor's '72 is different...

Yeah I was worried about that. I guess I'm not surprised... Especially when it comes to something "safety" related. I'm sure there were changing regulations and test procedures as well as constantly advancing research, understanding, and technology.
