Who makes the best underhood insulation pad clips?

I mean one's that bend and actually spring back not just bend and deform so you have to open them up and then they break.

I've had nice results with Auveco clips, the plastic ones anyway.

I used a set of the metal ones on my former challenger, Most broke before then snapped back into place( I have no idea where I bought them )

I ended up using the plastic ones as used on 1972 and up cars

If you have a NAPA nearby, they have a fastener book about the size and in the format of an 8 1/2 x 11 calendar. It has the fastener picture and sometimes even the OEM part number. Excellent reference. Maybe they have that type or similiar clip. worth a try.

can you post a pic of the ones you need?

Here are a couple of photo's

They are 1-3/4" long and 13/16" wide.

The one's I have that are painted semi-gloss black work better than the one's I have that are phosphate coated.
