Clips for hood insulation pad 65 Barracuda

I tried using the metal insulation clips that I bought from Laysons and they are useless. The spring steel lugs are too big for the holes and break off when forced. I could not get one to work and gave up.

I see Dante's has some @ $1.75 each, but if they are the poor quality with the same problem as the Layson's, I'd rather not waste any more money.
Anybody have a suggestion where I might find 22 of these? I've considered using the plastic ones which are much cheaper, but don't look right.

Thanks
