I am glad you brought this up, I have a 1.5yr old daughter that I will want to take with me on cruises etc... so I will have to build in some seat attachements myself during the build. Thanx for bringing the topic up. You can forget using a booster seat bewcause no shoulder harness, but you could continue to use a harness seat system.

Lap belts will secure the base of the car seat just as safely as those with shoulder harness'. You could also modify the rear deck to handle the strap that runs vertical on the car seats. Since they attach with small clips, drill a hole in the deck and attach a eyehole bolt, or some similar method. This way the seats are secured horizontally at the base, and the upper part of the car seat is secured to the rear deck and will not move forward at the top.

This will provide basicly the same secure mounting points as todays modern cars.

Also you could add your own latches to the lower seat just like the upper part. Remove the lower seat cushion, drill 4 holes that are spread out in the area just under the upper seat cushion. Then mount some eye hole bolts to the floor pan to simulate the little hooks found in the seat cracks of todays cars. Granted you would want strong bolts, washers, nuts, etc... since this new hardware is for safety.
