Want to Buy WTB or WTT: 18x24 film holders

I'm looking for some 18x24 film holders that fit in standard 8x10 backs. Lisco or Fidelity would be great, but any holder that fits in an 8x10 back would be fine. I'd be happy to trade some very nice 8x10 holders in exchange or purchase them outright. Thanks.

I have three 18x24 holders. One of them is a Lisco (marked "Sinar") and two of them are Fidelity deluxe.
PM me if they are of interest.
