When re-attaching the shifter to the linkage with the long bolt, there may be some difficulty getting the base of the shifter, with the new bushings, seated between the arms of the linkage. To make this part easier, I inserted a pair of pliers between those arms and stretched them out a bit.
I also taught Masters Students at Imperial for 3 years. The molecular formula for cyclohexane is C6H12, therefore one molecule of cyclohexane contains 6 carbon atoms and 12 hydrogen atoms. The relative atomic mass (RAM) of carbon is 12.011 g/mol. For hydrogen the RAM is 1.008 g/mol. Cyclohexane's molar mass is thus: (6 x 12.011) + (12 x 1.008) = 84.162 g/mol.
So if in any problem, mass (gram) of solute (w) is given then first we have to divide it by molar mass (molecular weight) of solute (W) in order to find the moles of solute (n) present in the solution, and again divide moles of solute (n) by volume (liter) of solution (V) in order to find molarity (M) or molar mass of solution. So we can also write this molar concentration formula (molarity) like this, Molar concentration (M) = $\frac{Mass\ of\ solute\ (w in grams)}{Molar\ mass\ of\ solute (W)} \times [Volume of solution (V in liter)]$
