rear D70 -$50 as seen in Forsale forum.

Rear D60 -$180 HERE

What are the pluses and minues of the D70? How hard would it be to convert to single rear hubs?

D60 has new brakes.

Trying to decide. Both are within a couple of hours of me.

all I know is the 70 will be a worse dragger than 10.25 and waaaay stronger than the 60 .......... if it were me and I wasn't putting anything bigger than 38's I would go with the 60 with the added piece of mind of having new brakes to boot ... it is a full float too!!!.... rebuilding the brakes on the 70 will quickly take it over the price of the 60...I would think

my 2 cents for what it's worth :shrug

Center of the tube to bottom of uncut diff measures about 6.5", about .5 to .75" more than a 60. I will likely shave it dramatically.

You don't have to convert anything to SRW hubs. What he has is probably a F350 chassis axle or something... that's why it's so wide. You'll have a hard time finding spare shafts for it... the good news is, you'll probably never need them.

D60 shafts snap like twigs.

Get the BOM on that D70, you can find out exactly what it is. If it has the offset pinion, it's worthless.

70Us have great housings... 70HDs and 70Bs, not so good.

Ok, let's re-visit broken 60 shafts:









These were all with 38" or 39.5" rubber and 460s...........but only one of them let go under heavy throttle, the others just loaded up slowly while crawling and let go. Based upon what I've seen I think a 60 rear would be *just barely adequate* with my 37's and 351, very little safety margin.
