I had a bunch of old alternators and asked at a place that (supposedly) rebuilds them, the guy said he gets most of his now from China, said it was about his only source anymore, scrap!
I had a couple of old standard trannys I was wanting to try and place, but no luck. I had other parts too, heads, manifolds, etc, and called an old junkyard, he said he only did body repair now, and didn't know of anyone who might be interested in any of it. I live in a sparsely populated area, and didn't really know of many choices, so I scrapped it, trannys and all. Sad part was two days later I went through town in a way I seldom go, and saw a transmission shop there
