WANTED OLD HOT WHEELS REDLINES (Sacramento)

Im looking for old hot wheels dating back to 1967 to 1977 i pay top dollar in cash and will travel anywhere, i have been doing this for a long time and i will travel anywhere to enhance my collection.
Im not looking for newer hot wheels from the last 20 to 30 years but the very first ones they have a red stripe on the tires and were made in Hong Kong or US patent pending.
Please help me, look in the attic or garage they are the ones that have been sitting in a box for years not even displayed or appreciated.
