Get a Jr. Dragster harness (4 point)
 

from summit. Pull the seat back and drill through the frame and use big washers and grade 8 bolts to attach the shoulder harness. Lap portion in the stock location.

I wonder if the use of a 4 point harness system would negate the requirement for a car seat? I mean it is functioning exactly as a car seat does with the harness is it not?

That looks like a great seat. I better start saving my pennies. I have twins. I would be into $600. Don't get me wrong, my kids are worth anything for their safety. I'm glad I started looking into this before I absolutely had to. Thanks for all the help Mike and everyone else. Anybody else have ideas?

I'm not afraid of designing and putting something together myself, but this is a touchy area I think. When it comes to the law, they may not interperate not having an actual "Approved" car seat. It gets a bit overwhelming. Not to say it was right, but I remeber jumping from the front seat to the back seat and playing with my toys when I was a kid. I think we all did. For a short cruise in a classic car I think my girls being lap belted in the back seat would be perfectly safe. I bet I would get a ticket if a cop saw me. I don't know! Thanks for the help.

I just found this. It looks like it answers my questions. At least in PA. Look under exceptions.

when i take my daughter with me on cruises in the 70 i just use the lap belt to secure the seat and it in there tight! grated shes only 1.5 so she still uses the integrated 5-point harness in the seat... but as far as seat goes this is perfect for us car nuts and it beats all in the saftey test due to thier side impact protection...lil pricey but when it comes to your baby its worth it.
when i got it 1/2 a year ago thier had more colors to chose from though, i got the charcoal one, its real sturdy and super high quality i reccomend it to everyone even non car nuts.lol but my girl looks super comfy in it.

Nice seat, Jay! Simpson also makes them for a full race look and there are lots of other options up to 80# so don't skimp or try to fab something yourself.

It might keep them from going through the windshield which only takes one jackass on a cell phone at a stop light to send a 45# 4 year old flying but if you don't attach the harnesses in just the right place or allow adjustment as they grow, who's to say there won't be internal damage of all kinds? Don't skimp on this and just throw down the $$ for seats that will hold an 80 pounder. There's lots to offer on the market if you shop around and to compensate for being in the "baby seat" when they're used to boosters, just call it their racing seats!

I agree with you guys. The kids safety is no place to skimp. I am happy that I found what the law actually is in PA. So often you think you are doing the right thing and oops, the police say not. I am going to look more into the seats. I'm glad there is a solution, now I just have to choose one. Thanks.

same seat we use, the way the seat hooks in it looks like it would be easy to fab some "U" bolts to secure the seat, i'm planning on putting some in very soon, here is our son in our mercedes....

oh by the way we did a road trip from santa barbara california to mt hood oregon and he nver ever fell forward in his car seat, ever. he loves his seat, we have had 3 differnt seat before this one and hands down he loves it, he is 4 and a half now and weighs about 45 lbs. and it has more growing room
