OK so we did it.
Their car
is a 2006. We installed in center with the seatbelt and top tether.
It was really wiggly at first, but we just kept on it and it got tight. really tight. Like not even 1" movement at the beltpath. If we shook it from other areas than the belt path, it had a little more wiggle, maybe an inch. This was all before hooking the tether.
It wasn't that hard so now I'm wondering if we did something wrong
I mean, it was not
easy, it took 2 of us. He was kneeling in the seat with both knees and I was pulling the seatblet tight at the same time. At first not even that worked because the female end of the passenger belt was right behind Radian (that thing barely sticks up out of the seat!!), preventing it from becoming fully tight. Then I pulled and held that out while he was still kneeling in the seat and he pulled up on the shoulder belt and it clicked a couple more times. Voila. Tight.
The only snag we hit was when It came time to tighten the Harness.
We added the safe stop because little guy is tiny. Like 36 lbs, but average height. I don't know what that did, but the harness is really hard to tighten.it was actually hard to adjust
before I added the safe stop because I was trying to extend it out far enough and it's just tough, but it got worse after the install. I was able to squeeze my hand back behind the seat and can't feel it hung up on anything
Ideas??
So they were happy with it, and so was I, as far as I can tell it's all good.
They are taking it out of town on a plane next week so I told them to keep an eye on it and see if it seems to loosen up or anything before then. If it does,when they get home we are going to try outboard with the seatbelt then LATCH, to see what we can get.If the seatbelt doesn't end up working, I think they can still get a lot of use out of this seat with just a LATCH install. This kid is likely to be 6 before he weighs over 48lbs.
feel free to let me know if I missed anything....thanks again for the help!!
