Traded a buddy a #489 3rd member case with 2.76 open diff for this unit. Good deal?;)
3.91 gears in the sure grip. The one I traded was an extra I had from the newyorker.Since the 489 case is not a Sure-Grip, i think i would do it. What gears are in the 741?
Will you put them in your fury? they are a lot of fun.3.91 gears in the sure grip. The one I traded was an extra I had from the newyorker.
That's the plan. I need to get the bugs worked out of the electrical system then the engine and then I'll throw this in.Will you put them in your fury? they are a lot of fun.
Now were talking lol, Better hurry while there is Still some Warm weather left.That's the plan. I need to get the bugs worked out of the electrical system then the engine and then I'll throw this in.
I did a similar deal with my buddy...I had a 2.76 SG in a 489 case and swapped for a 742 case with a 3.55 SG.. Good gear for a street car IMHO. You made a good trade..I doubt I'll ever run a single pass in the ole fury! Still nice to know I'll have grip if I do. I'm debating on putting a 3.55 on that sure grip and stuffing it in there. I'll probly run for the next summer tho.
Sure grips from a 741 I don't think will interchange with a 489.I just looked under the fury and I've got a 489 case in it now! Maybe I'll take that 3.55 I have, slap it on the site grip and stuff it in that 489. Need to make sure they will swap tho.
Great information!! Thanks for sharing that link! But alas they are not interchangeabElle. Ah well still have a sure grip!Dr Diff comparison from Moparts.

I don't think there is anything wrong with a 741 other than only a few gear choices available.

My mistake... I thought the different pinion sizes dictated which housing you could swap. Honestly I've only switched cases in and out and never had one completely apart.They will interchange you just have to switch the carrier bearings.
So the carrier bearings are case specific? Pinion gears make no difference?They will interchange you just have to switch the carrier bearings.
