if it's just for parts, resale of the actual frame itself must be all you're concerned about - so, having said that, I'd say "no" - the shortened frame will not be worth what an original shortbed frame will be worth. But the difference might be minimal - just a frame anyway. If done correctly, I wouldn't worry about it.

Couple things to look for -
- was it a straight cut or a staggered cut that is slid together? The latter is a bit stronger. If straight cut, fish plates to reinforce the weld are a must.

If straight cut, i.e. just chopped top to bottom, and no fish plates were used, you'll probably never be able to sell the frame as is.
