First I've heard of a longer stand being available, but I have firsthand experience with a bent bracket on a '96 Trident (and the associated mirror, lever, signal, etc., replacements...). It looks like shimming the stand or closing up the clevis the stand attaches to will fix it, but it won't. The front of the bracket will have bent a bit to the right, and will bend a bit more as more weight is placed on it, 'til it won't hold the bike up at all anymore. The solution is a beefier bracket from an '01-up Trophy. (Or so I've been told; it's actually VIN 55072 and up.)
One of the bolts that holds the bracket on screws into the case or the frame or something, but the other has a (19mm? head) nut on it that you can't see. Much easier to swap brackets if you know that nut is there...
