These are for vented rotors. To the best of my knowledge none were made for solid rotors. Guessing you could take out spacers and use new bolts. Brand new parts , no way of knowing manufacture date. Parts are not in US.

Seal kits are cheap and easy to install.
Yes you can remove the spacers for use on solid rotors but may need shorter bolts as they use partially threaded bolts. With spacers removed the short bolts work in place of the long bolts. Bolts a common cap head 12.8 grade bolt.
I think these only work on late struts unless you machine the ears.
