wanted: soft old pentax lenscaps

Hello,

I'm on a bit of an extreme macro binge which generally involves reversing the lenses I have. But I find I get better results if I make a hood that tapers down. And the most practical way to do this is to use one of the soft plastic k mount endcaps. Not the hard plastic ones that newer lenses come with nowadays, the soft older ones (that can be cut to make a hood). If anyone has some of those lying around and wants to swap them for the modern hard ones that'd be peachy.

Thanks!
