Fiberglass Hardtop - Rivnut?

I'm picking up a Hardtop soon, wondering if there is an alternative to using rivnuts. They guy I'm picking the hardtop from doesn't recommend them, because they can get loose and then trying to remove them can be a PITA.

Any thoughts on this???

I used regular hex head bolts on my top to attach it to the windscreen, then a couple in the back corners. The rest were black zip ties. Don't laugh, the top leaks a like a sieve anyway, and going the zip tie route will save you about 2 hours our of your life everytime you want to take off or reinstall the top.

It worked for me anyway. But then again, my 90 was kind of a pig.

Not really. There is no good access to the underside of the capping where a lot of the rivnuts go.

I've taken a look at the install pdf, but would appreciate if someone could post actual pictures or email them to me.

Thanks,

Ade

Rivnut

I have found with the fiberglass top the rivnuts strip out and you can't get the original equipment to work. I purchased longer stainless bolts to pass all the way through the stripped rivnut and then attach a nut and crank it down. I went from massive dripping to zero dripping once I went all the way around and checked all the bolts. I also made sure the rubber stripping was in place and in good shape.

I was fortunate to already have the rivnuts in place...I didn't realize what those were at first.

Anyways, it seems like the rivnuts in the rear of the truck on each side of the tailgate wasn't measures correctly, they are closer to the inside edge than it should be. Has anyone ever redrilled these before? Not exactly thrilled with the idea of doing so...

Old old post, but I need some advice related

I am taking off my hard top and a couple of the rivnuts are spinning freely in the tub making it nearly impossible to get the bolts out. The top of the tub has a rail that covers the "bottom" of the rivnuts. How in the heck do I get the bolts out/hang on to the rivnuts so they don't spin??

Thanks!

Some you can get to the bottom of, but most you can't. I would cut the heads off the bolts with a dremel. Depending on how tight they are you might get a sawsall between the top and the capping to cut the shaft of the bolt.

On rivnuts, if take a small file and key the hole it will help to prevent the rivnut from loosening and spinning when you need to pull the bolt later.

Thanks Ron. I used a dremel tool with a cutting wheel and successfully cut the head off of the two offending bolts.

I like the idead of notching the holes when I replace the rivnuts. Thanks.
