Refrigeration Circuit Done! And Other Bits...

Went to the car with the radiator, nosecone and refrigeration fan. Clamped the radiator to the chassis, trial fitted the nosecone and fine-tuned it's position. Removed nosecone and confirmed that I can attach the fan on the chassis later, without removing the radiator. Steve said I could brace the fan to the chassis, although there is a gap, refrigeration works well. Since Portugal has around 10º/15º more on the summer than the UK, I'm still unsure if I'll attach it that way or in a different one. Anyway, since that will be later...

With the radiator clamped, it was impossible to mark it for drilling, since the clamps were over the drilling areas. But the radiator is such a tight fix inside the cone that I was unsure how to do it. Ended up solving the issue the following way... With the radiator clamped, checked there in the chassis supports I should drill for best fit (offset to the interior on the upper ones and offset to the exterior on the lower ones). Removed the radiator and drilled the chassis. Then placed some paper masking tape on the radiator and clamped it on top. Fit the nosecone to ensure positioning. From behind, used a pencil to mark the radiator where to drill, putting the pencil through the holes in the chassis supports. Remove nosecone and radiator, drill, place masking tape on the top area, fit radiator (with bolts on the lower supports), fix nosecone, mark from behind the top holes on the masking tape. Remove cone and radiator, drill, attach radiator with the 4 bolts and nuts, trial fit nosecone to ensure success.
Having the radiator in place, attached the remaining hoses to it. One of them had to be cut to insert the therm sensor housing case. After taking the picture bellow, covered the casing hole with some masking tape, since I didn't have the sensor with me. With this, the refrigeration circuit is done!
Last task that I started was to trim the bulkhead, since it has a bit of excessive ally on the lip that prevents the hood to be correctly placed on top of the scuttle. Cutting ally with the dremmel is very time consuming and I had other things to do, so had to leave the job incomplete.
All the above tasks, including some cleaning up of the area around the car, took me around 3h and a half.
