VIN Info
I had alot of help from various web sources and from the Catalog of Firebird ID Numbers 1967-93. Also, the Catalog from Year One not only has all of the parts that you are looking for, but it also has alot of valuable information regarding VIN numbers, Production numbers, etc. For $7.95 it is worth ordering the catalog. If you place an order with them then the $7.95 is credited to your first order.
