STX RC 4-bolt spider

[old_coyote_pedaller]

I have a set of STX RC cranks with one of the lugs for the bolts broken off, I bought them for the rings.
Would like to put them on a bike now so does anyone have a spider going spare/for sale from a set of cranks that have knackered threads or tapers?

Like these, pic nicked off here.

Bump to say I'd buy a whole or part chainset with knackered threads/tapers just to get spider, don't think I made that clear in OP.

That's brilliant Eck, thanks.

Er, what's the wink for? Hope what I have to do in return doesnae involve lube.
