I have 6 sets as pictured and one set in my car and they all measure 290 mm from Center of bolt to end as mik has pictured in his measurements!
I know for fact one set are late ute and I'm unsure of others, I know I've bought some from stanza owners, and others from late utes and Sunnis but the all measure the same even bolt holes to Center of bolt



I also have also got 3 sets of early one coming unless Andy still has them maybe you can mod bolt spacing in early ones to suit!
When I had bought my coupe from Retrorally he had cut and shut x2 early sets 25mm longer than standed to give extra track but I've sold them, they were reinforced bottom and top and also had crush tube fitted inside to strengthen them, they would have been fine but it reduced ball joint options for me as I was going another way with my car!
