I'm definitely going to put a Dana 60 in my '99 Z28 auto. Anyone have any tips on how to do it? A friend recommended that I could weld the rear of the LCA's to the housing so I can ditch the torque arm. The only problem with that is I wouldn't be able to adjust pinion angle. Can I do this and just set it to -4* and call it good? Any suggestions would be greatly appreciated.

That's called a ladder-bar setup but ladder bars
are better constructed to buck axle torque, than
just globbing a weld to the LCA. Ladder bars are
usually (or sensibly) only for strip cars. The pinion
angle changes grossly with suspension travel.

You might be able to find ladder bar kits for third-gens
by now and that should be an easy adapt?

Dana 60 is like the heaviest passenger car rear end
ever made, are you really going to overpower a 9"
Ford?

yes

Strange is supposedly making a Dana 60 setup for the stock F-body suspension hook up.

that is the same thing i've heard should be way strong enough

You honestly think you are going to outpower a 9''? You can run those things forever in the 8s and 9s. What exactly are you packing that you make more power and can hook it better than the fastest f-bodies in the country?

No one has put a Dana 60 in there car without backhalving the car? Damn, hope I don't have to back-half it and go with a ladder-bar setup

You are going to add a TON of weight to your car. I don't think anyone has made enough power out of a gen III to destroy a well built 9-inch with an auto. Please tell us your setup, sounds pretty hardcore.

Sorry, I'm not telling the motor combo. I will say the car is getting a TH400 w/ transbrake and reverse manual valvebody. If I can ditch the torque arm, it'll save me from having to buy a Yank cross member with the torque arm mount on it (I cannot run a tunnel mount torque arm mount). With a Dana 60 and TH400, I'd just rather get rid of the torque arm altogether. This doesn't have to be a bolt-in install either. I can have anything someone thinks up fabricated.

I believe madman makes a ladder bar setup already, pretty nice one with pinion adjustment. I believe it welds on to your LCA (boxed type) and eliminates the torque arm.

What kind of 60' do you expect to warrant a D60 out of curiosity?, since your motor is top secret!

A Dany 60 is stronger then a 9"?

Couldn't tell ya cause I don't take my car to the track.

A local guy who has welded his LCA's and has no torque arm like I was wondering about said this:

I've never had to adjust my pinion angle so far, but you could keep that option with some fabrication. You could make the front mount brackets with 3 mounting holes to choose from. You'd either have to test fit each positon before you drilled those holes because the mount brackets would be welded into place and the length of the LCA does not change, OR add a length adjustment to the front of the LCA's as well. Having both would allow you to adjust the bite angle of the LCA's as well as small adjustments to the pinion angle.
