really to pin it to a day is very hard,there is various date codes on components around the car..instruments sometimes have them,heater boxes have them,steering columns have them and various other parts have them...and from collating all these bits to the month on your compliance plate you may figure it out...

ive been piecing my hq sandman together from a rolling shell since 2001..it only had its diff front suspension and gaurds and front doors..ive collected all the parts individually and tried to use date coded parts and heaps of nos with the largest and most crucial date coded part being the engine..i never thought i would find one but now i have so the build will begin in summer hopefully..
