Hi Mark,
1) We have them in stock.
2) We haven't heard of this issue where it would lose about 4.5" of travel. But if there are a number of people who experienced this, we would have to check it as well, please let us know of the link to the forum page that has this discussion.
We might have an alternative spring that you may add in, which replaces the included RacingBros aluminum spacer that would give additional travel if what they are saying on the forum is correct. The additional spring is 3.5" long. This spring is quite stiff, so it would come into play once the long spring is fully compressed.
3) Everything comes in a kit, therefore, we can only sell it as a kit unfortunately.
Here is the spring and spacer kit that you may purchase. I had measured and spec it out, this kit will replace the included RacingBros aluminum spacer:
