I have this listing on eBay UK:

It is the central carburetor mounting for twin carb set up.
I purchased this in a set of used mounts for my Alfetta GT (GTV)...but
Unfortunatly this in for cable operated carburetors...my car is not.
It is a used item but condition of important rubber part is as new
It has been removed from a decommissioned car and will need a little cleaning up before use.
Shipping cost may be a little high as I am located, Spain, Gran Canaria.
Offered at half price of new new item (EB Spares, UK)
