Can you identify what year this is from

[Guy67UK]

I have a 67 step side that has been converted to 5x5 hubs all the way around, and it has also had disc brakes fitted to the front. I assume that it is a 72 cross member but cant be certain. It does have the larger ball joints if that helps. I need to order some upper arms but cant identfiy what year..

Can anyone identify what I have from the pictures ? I know it may be a long shot but I have my fingers crossed

My trouble is I cant just order parts and quickly return them if I have the wrong year as I'm in the UK and some vendors want 5 times the cost of a part in shipping alone, it can make it very expensive so I would like to get it right first time if I can.
