I am pleased to report that we now have the first stage of the mechanical overhaul underway. As we work our way through the repairs we will also take the opportunity to correct a few points of originality along the way as the owner wants this car to be as original and concours correct as possible. For example, the DCOE 40 Webers currently installed are Spanish made. As production of Webers moved from Italy to Spain in the early 1990's, clearly these carbs cannot be correct for this car. Our research leads us to believe that the 350GT had Webers specific and unique to the 350, namely DCOE 40 (20) and DCOE 40 (21).

I am delighted to report that we will have this exciting project underway very shortly.
