The early part of this post is here if anyone cares.

I received a 4x5 Linhof Technika III "replacement" ground glass from Stephen Shuart. It is close enough to the correct size to fit inside the metal ground glass frame so thats good, but...
The two flat springs that push the glass up against the flat machined surface don't reach far enough to actually push against the glass. The amount of space left in there makes me wonder if this camera originally had a fresnel screen on it.

Did the 4x5 Technika III come with a fresnel and do I understand correctly that it was on the inside (lens side) of the ground glass?

If I buy a generic fresnel and ground glass, who should I contact to put it all together and make sure its all set correctly for sharp pictures?

thanks,
