In a van, down by the river
I currently have a 741 case, clutch type, that HAD 3.91 gears, before the pinion and ring gear were destroyed at the track last weekend. I am now finding out that 3.91 gears sets aren't readily available (new) for my case. So, now what do I do? Should I try to find another 3.91 gear set....replace the 3.91 with 3.73 or 3.55.....or just buy another center 489 or 742? I have a 489 SG with 3.91 gears, that I can borrow until I figure something out. Is the 741 worth the time and effort? It's mainly a street car that sees 10-12 passes at the track a year.


Got Mopar???

a 42 or 89 case, a new set of 3.91's because that ratio is right for your combo & use your sure grip & put it together.

Call Dr Diff, get the gears bearings & a clutch kit.. Then scrounge up a 489 or 742 case..

I have a spare 742 open case laying around if interested. PM me we can make a cheap deal. I have 2 and use neither of them.
