Right here is a brand new takeoff rear end for 999$.
I'm sure I could buy this but I'd rather buy a slightly used one.
I've contacted many people over eBay and Craigslist and everyone wants 1000+$ how in the world can you ask for 1000+ $ for a used gt rear end ..
I mean it's used .
Where will I have more luck in the Sacramento area finding a gt rear end? I just want to install a posi with 3.55 and finally get that power to the ground

I don't know why they are expensive, but from my experience, they can be bought for cheaper than $1,000 from private sellers. I picked mine up for about half that. The axle itself had around 120k on it. After I bought it, I picked up a rebuild kit, new gears, new t-lok and a new differential cover from AM. After everything was installed the axle was like new. Don't be afraid to buy a high mileage axle, you can always rebuild it.

Have you tried junk yards or something similar to that? Other forums?

New take-off and used sellers are different rear ends.
New take-off is just that, a new take-off.
A used rear end will have some miles on it and
be worth much less than that...

Before I had mine shipped from Oklahoma, I went to the gas station/service station a mile down the road from me and asked if I could ship it there. It was considerably cheaper than having it shipped to my house. Just a thought.

Why not just put a traction lock/posi unit into yours with a set of gears?

The size of the rear axle doesnt mean stronger, its the quality of the parts inside that does.

The 7.5" just can't handle the abuse that the 8.8" can. My car isn't a powerhouse by any means, but if/when I do start adding more power, it's good to know the 8.8" won't break on me after a couple of hard launches.

Also, it's cheaper in the long run to just buy an 8.8" than it would be to build a 7.5", break it, then build it up again.

Ring gear size is directly proportional to the strength of the
rear end and the abuse it will withstand.

Basic automotive knowledge...

All it took was a CAI, tune, and set of drag radials to break my 7.5 on the 2006 - added the tlok, Richmond gears (supposedly indestructible), and the LPW girdle for strength.

8.8 is definitely stronger. And you also assume that the parts can be found; Ford doesn't offer a tlok for the 7.5 anymore, probably for the reason below -- cost

Yes, cheaper to buy an 8.8 and swap it. Worst modding decision I ever made was to try to build a 7.5. It cost me more to build the 7.5 than the 8.8 cost me - and then to break and replace it with an 8.8 anyway was money tossed away.
