Can't seem to find these listed on any of the popular sites.

They seem to be a single-use push in type as I have destroyed every one I have taken out.

I don't need to use this particular type, are there other types that will fit in the hole these used?

 

I haven't seen that type on my 66s. I have some that are like flattened wire looped to make a retainer, and a part that goes into the hole. Others are like a 3/8" wide plate with a nub that goes into the hole, and bent over ends to retain the line. I have seen them reproduced; check the "usual suspects" and you should find them.

 

Maybe Toronado only?

Can't imagine why they would re design a line clip for a single model or year.

I'll have to check the hole size, I'd rather have clips that are re-usable.

 

Inline Tube has a selection of clips similar to the ones I have seen.
