i think my duster had them when it was new but they got lost somehow somewhere during 30years of changing owners 20times even if the car was put away more than half that time...
im thinking alitle furhter here, howabout triangulat all these points and have both a crossbar and keep the diagonalbars? should stiffen up the front of the car quite alot, im gona try that when my car is drivable again!
