You seem to have the first or very early DA-8 crankset which had flatter crank arms which resulted in longer BB which were fitted to my Trek 5500 OCLV, sorry no longer have that bike. Around 94 they released a more rounded profile but angled DA-8 crankset ( FC 7410 ) which shortened the BB to 103mm. I recently saw some of both types of the older square taper drive stuff on ebay you may want to check there for a number.
The BB you need may have to be wider than 103mm.
