Chinese fresnels for Linhof Technika IV

[Pieter]

I want to replace the fresnel that goes under the ground glass on a Linhof Technika IV. Has anyone used the fresnels that are sold on the auction site? Are they the same thickness as the original? Any quality issues? I haven't tried contacting sellers at this point, I don't know if they can or will tell me how thick the ones they sell are. Is the another source for the fresnel if those won't work?

I have had good quick response from Chinese and Taiwan eBay sellers
