Will this new threadless fork have a long enough steerer tube?

Hi. Total noob here. I haven't had a bike in about 30 years, but I decided to take it up again and I have a large framed Specialized Hardrock that I would guess is of mid-90s vintage.

So, I need a new fork because I truly demolished the old fork trying to remove a hopelessly stuck handlebar stem. I plan to also get a new threadless handlebar stem and a new headset, but one question at a time.

What I need to know is whether or not the steerer tube on this Dimension fork (260 mm - see link) will be long enough.

http://harriscyclery.net/product/dim...k0073-qc49.htm

By my measurement the (threaded Specialized) fork I removed is roughly 202 mm and the head tube on the Specialized frame is 183 mm. So, will the 260 mm threadless fork leave me enough room for a new headset and a threadless handlebar stem?

I hope I explained everything correctly. I did a lot of research online, but please let me know if it sounds like I have no idea what I'm talking about.

Figure 30mm or so for a headset (often less), and 50mm or so for the stem, so you need about 80mm more fork than the frame's head tube length. So at 77mm difference you're right at the edge. I expect that it'll be OK, but being so close you want to confirm

Start by going to the headset maker's site and getting the exact stack height. Also measure the height (thickness) of the stem, add the two, and compare to 77mm.

Thanks for that info. Maybe I should also ask on this thread for advice on a decent, reasonably priced headset?

Lots of nice headsets. You can get great value in traditional loose ball systems. Just look for one with low rise. You have 27mm or so to play with, but there are shorter ones which will give you more margin for error.
