i am looking for some leather seat upholstery kits like the vinyl ones you can by through year one or opg. In one of their catalogs it mentions leather but never gives any info or price on them. Does anyone know of a place that sells leather interior kits for a 66 chevelle? I guess i could contact Year One and OPGI

In the 2003 OPGI catalog (600 pages) page 30 (follows vinyl) lists leather upholstery;
'66 pair buckets.......$599.95
'66 split bench.........$599.95
'66 rear coupe.........$399.95
'66 rear convertible..$399.95
lists about every color imaginable.
