Why is this so dang hard?

Why is it so hard to fix something that isn't broke?
I have a "uni ped" 7.25 rear end with 2:73 gears behind a mildish 5.9 Magnum and 42RH overdrive trans in my Dart and have driven it thousands of miles with zero issues for years now.
I could literally stop at the gas station, fill up and take off out of state without so much as even opening the hood to check anything, it's that reliable.
Right now there is a 8.25 Sure Grip with 3:55 gears and disc brakes, full of fluid with the additive sitting on jack stands in my back yard ready to go in and I have everything to do the swap.

Why am I hesitating?:realcrazy:
It's just that hard to take something apart that already works I guess.

I could use the excuses, "It's a holiday season" or "It's 45 degrees" or any other excuse, but that's all they are.
We have 3 other cars I could drive while mine is being done, and a buddy has a garage and has offered to help.

I need that "Swift kick in the ***" my Dad used to threaten me with when I was a kid I guess.:lol:


It only took me a month to destroy my old 7 1/4 and 904 transmission behind a stock 318 with only a 4 barrel and headers, it's going go but when?

I blew 3 7 1/4" axles in my Barracuda within 4 years with a mild 318, 340 cam, stock dual plane intake, Holley 600 Vac secondary, and dual exhaust daily driver.... nothing special, just a nice daily driver that got 17.75 MPG highway...

The last straw was when the driver's side axle came out with the tire attached while I was driving down the highway and passed me on the shoulder... :BangHead: :steering: :wtf:

After that I swapped in an 8 3/4" with 3.23 sure grip and never had another axle problem... I drove that Barracuda to 500,000 miles.... I put a good 200,000 or more on the 8 3/4"...

With the sure grip and narrow tires, it went through snow better than the wife's Neon...
