The correct fawn cloth fabric for your car was factory installed. The pic of your current cloth is an aftermarket substitution.
SMS fabrics stocks many OEM classic fabrics and as I recall some ready made seat covers and headliners.
It's best to give them a call and request availability and samples.
There may be other suppliers that carry the correct cloth seat covers such as PUI, Legendary and Distinctive Interiors. Vendors for these suppliers include Summit, Jegs, Ecklers, SS396.com, Ground Up etc. which show pics of their offerings.
