Do I go for the complete 489 center or just a brand new sure grip?

there is no reason to run it... i have a spare 742 if u want but why waste money on a 50's center, just go a 42 or 89 and be done

I'm in Sweden and parts are very hard to come by for these axles. Thats why I'm interested in this complete case with a sure grip. Also it's at a good price, usually everything is really expencive over here. Cant take pictures because I dont own it.

If it not a weaker case then the 741 it will hold up for everthyng I have planned for my Duster.
