​Dave its not normal Chalk mate, it be more like welders type chalk marking stuff i assume, and it is a LJ Rat Trap.
And a Person who owns a Special Monaro that GMH owned and Experimental Engineering worked on has the same Pink markings on parts on his Monaro and a Ex Experimental Engineer told him they used Pink Colour to Mark the parts, that is how i found out about it.
I have used engineers chalk (pretty sure I still have some in my toolbox) and it will wash and wear off quite easily so I find it very hard to believe it will still be there on those components after 40+ years.
As I said it is not an LJ rat trap on your GTR. It is off a HT/HG 6cyl.
Yes
Talk to Ben
HHS know which 3-GTR's they are, HDT Took the Pink V8 Prototype to Calder for a Comparison Test on the 31/5/1972, Brocky drove the Pink V8 Prototype and Bondy drove the 6Cyl HDT LJ XU1, No doubt in the month of May is when Ian Tate had it to Drive and Ian said the Pink V8 Prototype only had 6 Cyl rego,
Al, which one of the GTR Prototypes was Harry Firth testing in mid April 1972?
