Now, I will only be putting down 300hp or so to the ground. But I will have slicks and be leaving at like 4k. Is the extra weight and hp loss of the 9 worth the extra strength? Will I even need the strength?

Buy a 9" housing for a '65/66 from Perogies (Perogie.com I think), use your 8" axles and brakes, get a junkyard center section nadinstall new gears and the locker.
Having said that, an 8" with a locker is pretty strong. Just don't launch with slicks and nitrous.....

$1200 would be to take out my 8 inch, cut the 9 inch housing to size, and put our axles, brakes, etc into a 9 inch housing with a new traction lock/locker and gears. That doesn't sound too bad too me.

What about launching an 8 inch on just slicks, no N20?

It's too risky for a $950 rear end. Consider the $300 insurance money well spent.

BUT, there are much cheaper ways to go... Have him cut down a 9" housing for your axles and brakes, and find a 4.11 center section w/trac-lock and 28 splines, from a wrecking yard! The track lock will be easier on your axles than a locker, and will bite very well at the track.
With the savings you could order a pair of 31 splined Moser axles for about $320. Then you won't have to worry about future upgrades. And 31 splined 4.11 trac-loc centers are a lot more common. We found our 28 splined 4.11 geared center from a '67 Bronco.

Good Luck in the hunt,

Insurance......I never though of it like that. That is an interesting idea, about hunting the junkyards. Although from what I hear, lots of 9 inch rears have already been pilfered from junkyards.

Good Luck! Ryan

No it's from my friend's Bronco. He upgraded to 31 splined Currie axles and a air lockers. The same guy that donated a 11" Centerforce Dual Friction clutch that he no longer needed after installing the Motorsports 5.0 motor that came with a clutch. In fact the our old 289 engine was from his Bronco too. Maybe I should take him out for lunch. Or maybe he should buy, seeing as how I cleaned his garage out for him.

The 8" would be wasting money, they are NOT strong, the spindly little caps will break off it with any power and hook. A 9" would be better, an 8.8 will also work. $1200 is no raving pbargain, new gears and locker would be around $500 and doing the housing you supply should be in the $100-150 range.

---

I don't know..... A locker is at least $400 and I thought gears were like $180. So that's $600. Then you gotta get a 3rd member and housing, then you gotta think about labor. Since I am in college, I have no place to do any labor of this magnitude, so it would have to be done (correctly) by a pro.

Chip,

The 9" rear that we started with was the correct width for a '65/'66 it was from a 57/58 Ford or Edsel wagon w/v-8. We twisted/bent the old 28 spline axles pretty quick. It has Moser 28 sp axles now. Still a 28 spline diff. from the '67 Bronco w/ Trac-Loc. So far so good, but still only 1.68 60'ers so far. The 8" is ok, but eventually you'll out grow it.

What is Equalock? I assume it is like traction lock/posi/limited slip?

EquaLock was what Ford had before TracLock. Both are limited slip differentials. It's all in the "name"

So I assume it can be rebuilt like a T-lock?

...If you're looking for easy, you might better take up riding a bike! No one said it WOULD BE easy and who REALLY wants it easy anyway? I know a gal that's easy, but she's not my pick for a date! Remember that the JOURNEY to the top is way better than just SITTING on the top!

I saw that. Currie has the same thing for $895 with locker, $850 for trac-loc.
