RE forks, you probably have what, 2.5 inch travel fork? For all intents and purposes you want a non-suspension corrected fork.
There's about a bajillion vintage cromo forks out there, I picked up two on ebay for <$35 recently and coulda paid less at the bike co-op. I guess GT was sourcing Spinner forks, they are out there. Looks a *lot* like a specialized fork, if you don't mind rattle-canning the thing. I tend to prefer Tange, which are prettier (if you want that) or equally burly (the "Big Fork") if that's your thing. Some of those Tange forks are really heavy, if that's of concern. Trek was sourcing "Lung" forks at the time, in spite of the goofy name those are pretty decent imo. Most of those vintage forks will be ~ 395mm or so, maybe a smidge shorter than you need, depending on what they did with that frame when the first sus forks came out... shouldn't hurt anything especially for street use
Be mindful of your steerer size, in the mid-90's there were a lot of changes going on... looks to me like you have 1 1/8 threadless but
measure and be sure
Also check out the Kona P2 fork, those are harder to find used but are kinda different and should add/hold value.
Carver has a clone of the P2 that's very reasonably priced if you prefer to go new, at 410mm it should be about perfect for your frame
The Surly Troll fork is still available, it's a bit longer at 420mm but still in the "non suspension corrected" range. I think they are ugly but plenty of mounting points for racks and whatnot
Check out the Stridsland website, it's a better option for people in Europe than the US because of shipping costs but he has a cool fork and some single speed chainrings in hard-to-find sizes
I'd consider the bike co-op thing, get a fork for cheap and they will help you install it right there.
Rattle can it when you get home
