No the 3k was for everything. Even mounting the body, doors and bed back on the frame.

The border was easy. When I took the fenders, bed and doors down Mexico charged me an temporary import tax of $100. They want to make sure you aren't dumping stuff there. When i took the cab down I just showed them the registration and they checked vin number and we were good to go, no charge. When we took the frame down they looked at the vin on frame and no charge. When i bring it back it will be together and US customs will be ok with the registration.
