Soft Top Blew Off at Highway Speeds

I've looked & can't seem to find this problem.
Coming back from Ouray & almost 200 miles from home, truck passing by and the trucks draft "deflated" the top & as it finished passing by top went back to "inflated" then came loose at that rail that goes into the channel. Literally had the top wanting to blow off from the front if it hadn't been for the snaps on either side. Pulled over didn't see anything really obvious, tucked it back into the channel but came back off after a few miles or so. Not so scary after a coupla 2-3 times. Finally duct taped it in place & made it home. The metal bar in the sleeve that gets tucked into the channel appears to be bent (probly stretched from all the getting blown loose) but it's a soft bend, nothing right angled or anything. Called RN & they hadn't heard of this &suggested the windshield channel might've got bent or something. It's still taped in place & can get around short distances but obviously not gonna drive like this.
Any suggestions?

Which brand top? Had this happen to me years ago in a jeep. Nearly wrecked on the interstate.

Let's see pics of your windshield channel that is screwed into your windshield, as well as pics of the top and detailed shots of the windshield portion of the top. Tickford tops are supposed to be able to come undone from the windshield portion so that the top is still secured in the rear section but the front occupants are "in the sun" if you will.

This (per the official instructions and my experience) cannot be done without completely detaching the rest of the top from the truck, removing the front bar from the windshield channel and then completely reinstalling the rest of the top. Not a practical design for 'on the fly' sunshine.

BTW, my Tickford had similar gusts/buffeting from trucks on the interstate last weekend, but nothing that caused it to pop off.

Mine has billowed up a lot before but never come out from the front channel. It can sometimes feel like that and I can fit my fingertips in there to feel where the bar slips into the channel. Remember that bar is flat and is really only held in there by the slim fit and surrounding snaps

Just rereading your original post. Are you saying you were able to re-insert the front of the top into the header bar without removing anything else? If so, something isn't right there. With the top properly attached, that bar should be pulling toward the back of the truck, unless it was never seated properly in the first place, which is always a possibility.

The header bar is always where you start installation, and end removal.

Yea, I had re-inserted the header bar into the header channel easily enough for the highway fix. The header bar & channel appears to be OK. The pads were good & snug over the roll bars. The snaps on either side of the windshield were the only thing that kept the top from blowing completely back. I talked to Badger & he thinks the gutter kit may be the problem The Tickford doesn't have the footman loops, velcro straps etc. to completely finish the install. I'm gonna try & get pics to him this week & will post updates as soon as I have em.
Thanx for all of y'alls comments & suggests, please keep em coming

OK, Eagle Eyes here's the pics. Sent these to Badger & he shad a few suggestions. Velcro loops for the foot loops. Adjust the windshield, move it slightly forward. Move weather stripping around.
Gonna send 3 more pics in a separate reply in just a sec.
Thanx guys.

I'll have to admit to never seeing a Tickford with a gutter kit. Does that mean you don't have the velcro and snaps on the bars that connect the B-Pillar to the A-Pillar? That may be something to look into. Also, looks like the metal insert isn't long enough for your top to completely fit into the header bar.

Are these OEM parts or did someone make these parts for you? Your header bar appears to have too much space and it may be facing up a bit - I could see that causing some issues for sure. Search around here for what those parts should look like.

Perhaps it is the photo, but is the header bar lifting from the windscreen on the right hand side.. Assume this is bolted down ar all points. Tim

Horsey I agree. I think this pic shows the issue - the header bar looks damaged and there is too much space. Im thinking this space is the intrusion point for wind gusts to make everything come undone. I too have never seen a Tickford gutter kit and wondering if its OEM. Looks cool though and I do like the OEM look of the Tickford top.

As far as I know & can tell it is the original Tickford along with all the other top parts. And no, it does not come with the velcro loops, etc. That was one of the things that Chris/Badger said needed to be done. The velcro strap on the B pillar was good n snug(the one above the seats right?) The header bar gap opening on both sides does look worse in the pics than it does live & may just get replaced cuz if nothing else it, along with the bar, probably got stretched open during the multiple pop-offs. Once the tension is taken off that bar on the front of the top it really gets wavy lookin. I've only had the top off once to install the gutter kit & I don't remember it being that curvy. Anyone know the dimensions of that bar? RN didn't have it.

Im not sure but the NAS header bar may be NLA. Im sure someone will hook you up. when you source one, don't toss your old one because someone may want it & repair it.
I had an extra NAS header bar back in the day, but gave it to a d90 yahoo board member more than 10 years ago and I wish I still had it.
