Leaf spring bushing question

[kurts704]

I have a 67 K10. The leaf spring bushings in my truck are one peice. A big steel sleeve with rubber and the smaller sleeve in the middle that the bolt goes through. I need to replace all of them. The only stock type like mine I can find are $16 each. Kinds pricey for me. The polyuerothane ones are three peices, the sleeve the bolt passes through and two outer side bushings. Do these outer bushings slide right into the leaf spring eyelet or do I need the big outer sleeve like on my stock ones? Because my outer sleeves are shot. None of the restoration places can answer this question, those guys are useless, so I'm going to the pros! Thanks in advance.
