Ah! the joy of reaching out in the box or on the shelf to grab the new part when you need it. ..only if you have collected everything you need.
I even have the screws, nuts, bolts and washers cleaned, de-greased, (and at one point cad plated) for when I am putting it all together. (there is a person in Rawalpindi who cadmium plates nuts and bolts. If you can get original spare hardware from the countless Dalda tins at the old repair shops you can have them treated and ready when your car is ready to receive them.)
