Distributor question

Wasn't looking to pick fights or anything, though I really wanted to know what others thought, I didn't think I'd be the only one...
Sometimes I ask what I do for " looking at an issue from devil's advocate" point of view.
But on my used and "self rebuilt" distributor the old gear just kind of crumbled when I went to knock the pin out of it and I have to replace it with "something".
I had the 1st steel gear already and I figured instead of ordering something that these days will probably either come from China, or has sat in a shelf for 30 years, I thought I'd just use what I already have. And then Zilla posted that 2nd one on the other site (he's who I got my 1st one from, too) I just figured I'd put it out there.
I honestly thought they got discontinued because they don't make a /6 anymore and reverting to "only the plastic version" was a way of parts makers going cheap. As is so common now a days.
Or did they discontinue the steel one because of an actual problem with them?
I see that the Aussies also have a 3rd choice (bronze I believe) but since the only way I can get that one is by paying more to ship it than the thing even costs to buy I wasn't even considering that choice.
My current project is pretty much for a daily driver in a truck, not a race situation. That might change some people's answer (or not) might occasionally do a little bit of (light) towing of a garden tractor or 2.

Next question (it was asked also in a previous reply to this thread) is there a shelf life to the plastic/nylon ones?
I realize that even though "old" a new one that's lived on a shelf for umpteen years hasn't been subject to the heat/cool cycles like one that's been running an engine for years.
1st, if it's packaged, & not sitting in the sun...it should fly fine.
2nd, You really need to heed My above post, and here's why...
