Thank you guys,
I look for FW type, not FX. I corrected my post. Yes there are some on ebay but the shipping is too expensive to Turkey so it makes almost a price of an as-is body.
Another question, it isn't clear whether RTS screens would fit to RX or not, RTS's screens has no type subscript so it is doubious. They look very much like FW type. I wonder if I buy one, as-is RTS and risk it.
Also KEH has an AX non-working on ebay and AX uses the same FW type screens.
Does any pf you have RTS body? If I have the dimensions I would see. I know that the thickness is what matters. Mine is 35.9x24.1x1.4mm with a tab.
