yes just have to get the correct bearings for the sure grip to case
 
Yes the sure grip will interchange between the 489 and 742 case I’ve done it but not sure about the 741 case though.
 
It will work in all 3 cases, 489 has bigger O.D. bearings
 
I spoke with a guy today that does alot of sure grip set ups, said they can swap into a 741 as well.
 
If the bearings and races are good than you can install your SG in any case 741,742 or 489. The bearing/race set up are specific to the type SG you have., Cone or Clutch. Just get the same part numbers you have now on there.

I said it wrong it's the I.D. that is bigger on the Borg Warner cone clutch 70 - up 489 case
The Dana Power lok sure grip 57 - 69 741, 742 cases use the same bearings
So the power lok will fit in all 3 cases
