I have a bit of experience with salvage vehicles. Normally when completely repaired they are worth about 80% of the book value. I purchased my 01 Tundra 2 years ago with about exactly the same damage you are describing. It booked out at about 16K and I paid 5K for it and had to put another 4K into it. Now this has a "insurance claim paid" title, which is not a salvage title, but something between clean title and salvage. Salvage title usually means 70%+ of the vehicle value would have been required in repair cost. Salvage titles also require inspections in most states.
Here is a 98 Limited that is wrecked going for 5K. This damage is harder to repair than what you are describing: http://www.43autosales.com/511e11.htm
Just to give you an idea. Good luck with the sale!
EDIT: i guess i read it too fast and didnt notice that you fixed it.
