I am posting this on behalf of a guy I just heard from today. Bill Tillitt here in Springfield called and told me he owned a GT and needed some parts. I told him his best bet was to try ebay but he is not an online guy. I guess he has bought some stuff from USA Opels and is happy with what he got but would like to find some of this stuff closer to home. If you would like to contact him by phone he can be reached at the following number after 6:00PM 217-753-3641. He said he needed some motor mounts, a gas tank sending unit, An exhaust manifold and a few other things. His GT is his daily driver so he is not looking for show parts.
Thanks
John
