Fits original U-20 manifold.  Excellent hand machined and finished part.  Exact copy. 
 
Correct plating.  PERFECT for 100 pt restorations and any top quality U20. Includes rear heater fitting.
 
A couple dollars more for a MUCH better,  USA production, show car quality part. (Not a budget copy!)
These parts are brazed and plated just like the original. Concourse correct in every way.
 
Before you buy the poorly made 80$  Datsun-amateur-part, take a close look at his photos,  the part is pressed together with green Loctite, a hope and a prayer..... It will work just great until the Loctite lets go and sprays hot coolant all over your engine compartment.   The correctly manufactured original parts lasted 50 years, which would you rather have?
