D you wrote quite a lot about the E16 crankshaft [same as lemonhead is using] and i had a look at the wiki and some other sites. I am still not sure if this was sold in south africa. Info wiki gives is nissan sentra fwd 1982 ---1988 and i think it is 1600. I know there were 2 types of sentras sold --box type with long rect rear lights and one with corner lights. Wiki shows b12 and b13 --so are they found in these vehicles and why is it called e16 crank.

E16 is 1.6 liter version of Nissan E Engine. E15 has a crank identical to A15 but E16 crank has a longer stroke
