During the assembly of the frame I realised that the layout - i.e. both axles in line with the frame section did not lend itself to low slung lines of the Brabham. To remedy this I decided to drop the frame by 100mm below the axle plane. This was done by installing a couple of standoff brackets between the frame and front end, with a short section of REO as extra support:
And a couple of 100 x 50 mm sections between the frame and the rear bearings.
Giving a better ground hugging profile:
Once the frame was established the motor mount sections could be assembled, leaving a void for the torque converter to sit slightly lower than the frame.
Moving on to the nose section, I found some stainless steel spa pipes, cut down their length and joined together with a short steel inner steel pipe section.
