Vintage Moroso T-handle aluminum shift knob.   

This is a nice original solid aluminum knob. Has a larger thread size, possibly 1/2" coarse but I'm not sure (Adapters are pretty easy to find but please be sure this works for you before purchase.) 
This was pre-owned so may not be perfect but is in very good shape considering the age. There are No cracks, breaks, or pitting. Threads look to be in good shape. (Photos show condition)  Overall a very cool and hard to find original custom knob for your ride or for the collector.  Take a look...

Please be sure to look over the photos carefully and confirm the condition is acceptable and that the item is correct for your application Before bidding.  
Shipping to U.S. addresses only unless using Ebay's Global Shipping.  Thanks!
