Step Two:
Top engine mount (head bracket) plates
On either side, are the two (not to scale) templates for the 2 sets of top plates that you will need to have on hand in order to build a Vincati (additional commentary appears below the complete image):

Blue lines: These lines are an aid to enable the visualization of plate location once they become welded, integral frame components. Note also the two blue slashes on the Ducati frame. These lines represent the two needed crosstubes, most conveniently cut from the loose front down tubes. The four plates you will need to have made hang on those tubes when everything is in place. The plate's open holes are there to admit the existing cross tubes. These anchoring points are critical in the construction phase as they enable you to handcraft each tube while the motor is in position. In our experience the front plate required little modification; the rear however traverses quite deeply before coming to rest and some opening up was required.
The Bright Red lines: These lines highlight bolt fitment between the plates and the Vincent motor's headbracket mounts (identified in the Parts Book as FT3).
The Orange lines: With close examination you can see the brackets in place on the photograph of the motor. The side by side comparison of the Vincent's upper frame mount with that of the Ducati yields endless insights. On a more practical level, I should note that that big black box the Vincent uses for the top of its frame is the oil tank, so with its elimination, a minor need arises, that being the mounting of a peripherial oil tank. We are running one off a Norton 750 Commando positioned behind the left side cover. It fits snugly into that triangular opening (sort of boxed by my blue line) to the rear of the engine. (Visible in the diagram is the battery tray; the oil tank lives just over from there; if you look closely the tabs used to secure the side covers are also visible.)
In addition, you will need to fabricate two plates designed to bridge the two involved mounting platforms at the point of the swing arm and they are presented, here.
