I have a Pletscher double leg kickstand that has been installed on a regular commuting bike for about 18 months. It got out of alignment, and I was trying to remove it to re-install it. Unfortunately I managed to round the allen key hole at the top of the bolt (!) and ended up having to drill out the head to remove it.

Now I can't get the end of the bolt out of the kickstand body. I think that it's galled (chemically corroded) because the bolt is steel and the body is aluminum. grrr.

Has anyone had a problem with this? I've tried copious amounts of PB blaster, heating the bolt with a torch, putting the body of the stand in a vise and using visegrips on the bolt, all to no avail.

I'd like to reinstall the damn thing, but have to get the bolt out, and am not inclined to buy a new one if the dissimilar metals are going to be a problem again..
