Is this a 489?

If the components of the pumpkin are matched then not an issue.

In my case I misplaced my buttons for the Dana center and 742 case and just put a cone unit in from a 489 case with the 4.56 ring gear. Was not an issue until swapping in 3.55 gears. Ended up having a shop shave the pinion head on a lathe to get the clearance.
