This is a part from our HUGE collection of Classic, mostly NOS parts.
Please note NOS parts can be very old and have some rust, dust and possibly some spider webs - We clean all this off for the most part but some may still be on the part when you receive it.


We typically ship within one business day!  International buyers are responsible for any customs/duty fees.
Most of the parts we sell are vintage New Old Stock parts. We are have identified fitment information to the best of our knowledge in the description of this listing or the Compatibility Table.  It is possible this part fits other vehicles.  If you have fitment concerns, please contact us.

We use high quality shipping supplies and biodegradable peanuts to make sure your parts arrive safely. 

NOS (New Old Stock) parts are Genuine Factory Original parts.
NORS (New Old Replacement Stock) parts are original vintage aftermarket parts.
NOS and NORS does not necessarily mean the parts are perfect.
Manufacturing technology was not the same as it is today so imperfections should be expected.
Also, these parts may have been in storage for 40-80 years and could be dusty, greasy or have surface rust, spider webs, etc.
