Penn 114 spools

[jeff smith]

Guys,
I have three (metal bar) 114 Senators and I wish to purchase(used) a spare spool for each of them so I can have one spool with mono(sharks), one with spectra(common skate), for each reel. My current spools are the metal version (one piece) but I understand that an alloy spool was fitted to these reels later on. Will these fit? Not too worried as metal spools will do-just asking. Were three piece spools made for these reels? I understand I should avoid them?
I've posted in the classified section but while I'm on here, does anyone have any spares they're willing to sell? I'm not too worried about cosmetic condition (corrosion no problem) as long as they run true. I'm in the U.K but will of course sort out shipping.
Also, I still need a complete set of rings for one reel if anyone has any knocking about.
