I'll only speak to what I know, a florida "salvage" title cant be put back on the road in florida. it's a newer law. in talking to my insurance agent earlier this week, her son wrecked a custom truck and they totaled it and paid 3K, however she could have bought it back to fix up or sell but it couldnt have been put back on the road in FL. The new law in florida was put in place to stop some people who were re-building wrecked cars and selling them as never wrecked.
I suggest you also look into how Texas looks at that title comming from another state. I would also confirm that (once you know how Texas would re-title it) you can get the insurance you need on it.
