1970 Duster AlterKtion, 4 Link, LS/T56/Turbo and Minitub

Just a small update here. Kind of ran into a snowball like every typical project >.<

I had bought a new Yukon 3rd member for the 8.75. Then decided that I was just going to break that again and had a good Dana 60 laying around so I started doing some homework. I thought the 60 was going to weigh much more than a 9" or 8.75, and I already had the rear disc conversion kit from Dr. Diff so I really wanted to retain that and the working Ebrake. After some research I found a few different things:

The semi float dana 60 is actually 35lbs LIGHTER than a 9"
Axle Weights

Mancini and Doctor Diff make weld on flange ends to accept the 8.75 brakes and green bearings
Moser Engineering Rear Axle Housing Ends

Dr Diff makes a BAD *** calculator for cutting down a 60 to work in our cars.
DoctorDiff Housing/Axle Calculator

So after these findings, I put together an order from Dr. Diff for some 35 spline shafts, suregrip posi, 4.10 gears, master rebuild kit, axles seals, new flange bolts and a new 1350 yoke. I'll have about $1600 in parts for the 60 which is what I spent on a new 3rd member for the 8.75 (I already have sold now to cover that cost) but will be able to handle 1000hp or so from what I've read.

With great horsepower comes great parts upgrades. sigh... so while the rear axle is out I pulled the T56 to upgrade the clutch because I had the 800hp clutch in the car before with only mid 600hp expectations. When the car made 780 on the dyno I knew I messed up. So I sent that clutch back to be upgraded to the 1200hp clutch.

While the trans was out I started an argument with myself saying the T56 will be the new weakest link (being good for 6-700hp) and while its out and functioning well I should sell it to recoup my $2000 I paid for it. So before it turned into a pile broken parts I decided to bite the bullet on the new T56 Magnum F. The bright side of this is I'll have the .68:1 double overdrive instead of the useless .5:1.

Long story short a quick 8.75 fix turned into a $6000 winter upgrade Ramen noodle festival. My ol man always said "you have to pay to be cool" when I was younger and now I'm understanding this phrase all too well haha.
