Yes, there are a few places to get longer, bolt on hard tails for pre unit frames. Depending on the year, the later pre units where swing arm frames- still, you can get bolt on hard tails for those as well.
DON"T listen to anyone who says just cop out and find a unit construction bike. That's just plain dumb. Theres a good reason the pre unit stuff is more expensive; Pre units always have been and always will be cooler than a unit ever dreamed about being. Its a fact.
