Here I'm back again with the 640 WIP. I had a little brake since my last post to do some other works. Someone could believe I quit the project, but I changed my strategy thanks JamesB's post.
JamesB is right: indeed there are all drawings with the curved lateral tanks, but you can never find that on photos.
So I decided to make a new chassis and let the original Tamiya chassis unchanged, only the central fuel tank in the driver's back was lowered as described before.

The front of the side pods air intake is in line with the front of the cockpit cowling marked by the yellow tape. But the pics show a larger distance and straight front part of the side cowling before the curvation and should be longer.So I have to enlarge the air intake at the side walls and at the main cowling.

The forward movement of the cowling is not compatible with the expense of the upper and lower uprights. That requires a smaller angle of the uprights and new rear supports.They were moved forward for 6 mm.

That includes the upright openings in the lateral walls. They were cut out and replaced to the opposite side.

The Tamina tank opening on top of the chassis is not very satisfying, so I revised it. Holes were filled with putty, and the opening was enlarged with the mill and later on will be covered by an all sheet with holes for the screws.

Think this picture was missed in the last post. It shows the replaced and glued part to the opposite.
