Loooking for 9" 3rd member?
Loooking for 9" 3rd member? What are some of the ford cars/trucks that i should look into, i would like to find a posi & 31 spline if possible, should i narrow it down to certain years/models? Any info would be greatly appriciated. I'm in the process of getting a housing/axle package from EPP.
, they surely have to be stronger then them right 
, i don't mind re-doing the 3rd. member, new gears/bearings & most likely a spool, but if i can find a posi in a bone yard, that would be great, will they be most likely in the trucks? Used in some Fords, Mercs, and Lincolns 1957-1986. Look for it in vans, Broncos, pick ups, and some cars.

To clarify, the factory ones don't suck, but they will only hold up to about 400rwhp with 5500k-6000k launches. They will hold for a little while, but eventually let go. My buddy ran his for about 3yrs cam only with a very light camaro (stripper model that was gutted for racing) so depending on weight. You can check ebay also, or look on here. I found an aluminum moser center ready to go for about $680 shipped from a member.
Thanks, i found a junkyard that will take 75.00 for a 3rd. member, it might be the C7AW-E 31 spline, is this a good price, or what should i pay for one?
BTW, i'll most likely install new gears & go with a spool, so that alone should crank up the strength would you say?

That's a good price, but the gears and the spool aren't what's going to break. It usually breaks on the inside where the pinion comes through or at the bearings. It will be good though for occasional racing on sticky tires. You shouldn't have to worry about it. Unless you plan going to an all out drag car then you might as well spend the money and get a good one.

The most it will see is no more then 380-400rwhp with a 100 shot, most of the time it'll be with just a bolt-on engine with no more then 300rwhp, i just want it to hold up so i can lauch hard enough for good 60fts., so if this 9" can't hold 300rwhp then somethings wrong, all i know is i'm not willing to chance it with the 10 bolt. I was told by a few that even the standard 9" houseing is good for 500rwhp without too much worry.
Check Ebay or a second chance race parts place and you'll find one for sure... It just seems retarded to me to put 30 year old JUNKyark parts in a performance vehicle...Just do it right the first time... It dosne have to be some super throw down aluminum 3rd member.....It seems people are always at extreme ends of the spectrum on drivetrain... Overkill or a band aid....

I would save up a little longer and not opt for a soft iron 3rd member.....your doing everything correct IMHO with the exception of the 3rd member... you have stated that the car wil see 380 400 whp with a 100 shot which will put you close to 500 or over...failures will happen at the worst time... I know this from a few years of experence...hindsight is always 20/20 if you wanted to use only a few new parts like bearings or a ring and pinion then I would tend to agree with the junkyard theory.. but your soo close to having a kick *** set up dont let 75 dollars worth or iron 3rd member ruin 300 or 400 hundred dollars or driveshaft ,ring and pinion and carrier .. I have seen a pinion blow right out the front of a gear... H case with Iron Daytona pinion support 700 dollar motive gears and a 600 dollar locker... and it went right in the trash... only thing saved was the ring gear bolts.....

Yeah, that would be a much better way to go. All you'll need is the bearings, ring and pinon, and the spool which is what you would be doing any way. Atleast this way you won't have to worry about the any of it. The junkyard is the absolute cheapest way, but there are other ways that are better and only cost a couple hundred more. Your gonna love this setup so much you'll be glad you didn't cheap it out. Trust me. I just got mine a few weeks ago, went to the track last friday and I still have a smile on my face lol.

Thanks, if i would have known about those new N cases, i wouldn't have even been asking any Qs on this, they even have great prices on spools too, i know i'll need a pinion support, but there just 85.00 & the spools around 100.00, glad i dug around
