With the new engine in my 67 Barracuda, I went to track and twisted the housing. The 408 dynoed 606hp at 6300rpm and 553 lbs at 5100 rpm.

The housing gave up, so there are 3 options for me:

1-Change the housing and brace it with the mopar brace

2-Go with a Moser axle housing cut to length

3-Go with a Dana 60

I already have 35 spline spool and axles

What would be my best option for reasonable price ? Any ideas welcome............
I'm running ladder bars

Either Moser housing or brace another stock one, depending on what you want to spend. Braced stock one one would live fine IMO.

I would recommend the Dana 60 solution. You should be able to reuse your 35 spline axles and brakes. Truck Dana housings are easy to find for less than $200.00. Make sure the side carrier bearing has not spun in the housing to avoid additional machining costs (common problem, easily fixed). You will need to buy a new spool, bearings, seals, gears, companion flange, housing ends, ladder bar mounts, and shorten the driveshaft, but altogether (with your existing axles and brakes) you should be able to permanently solve your rear end troubles for less than $1,000.00. Check with Dr. Diff on prices. And you could sell the 8&3/4 carrier and spool to make up for a lot of the difference. And once you have a bullet-proof rear end, you can almost forget about the major reason that 727s explode.

I run a braced 8-3/4" in my junk. I do not run a transbrake. Best 60' 1.42, normally 1.45. I made the brace myself from a piece 6.0" X 2.0" X 1/8" RETU along with a little help the tube laser at work. I have never had any issues. However I do not think I would run a brake with that set up.

We run this same set-up, 30 spline axles even. We have been 1.28 60ft (no transbrake) and our rearend troubles are gone. We twisted a backbraced 8 3/4 and broke multiple pumpkins which led to broken sprags.. Once you add more power you will be glad you went dana..

I agree with the Dana, best thing I did ! Don't get me wrong we ran the 8 3/4 back braced spool axles and didn't break but I was worried ! Weight kills them ! If you can sell off what you have and get the Dana !

And from what model truck should I get a cheap housing and best supplier for parts ?
I take it the Dana from trucks are sufficient ?

I would not put any money into an 8.75! Dana or 9". If you ever upgrade to a higher HP engine the Dana or 9" will hold up. The rear is one part that overkill is good.

If you can find a truck or van dana 60 housing that has the three (3.0) diameter axle tubes buy it quick take your time looking, if you can't find one of those then look at buying the next size axle tubes that are 3 1/8, some are even 3 1/4 diameter , I would stay away from them BTW some fo the GM and GMC early(1970 and earlier ) 3/4 ton pickups had those and I think even some of the early Dodge and Ford pickups had them also. I'm not exactly sure when Dana Corp. started making the Dana 60 with 3 1/8 axle tubes

I had Strange 35 spline race axles special made to work with the stock A body 8 3/4 housing with the strange 35 spline 8 3/4 spool, I twisted that rascal(houusing) up horribly with no back brace. I swapped the axles over to the truck Dana 60 I had narrowed and I had to cut about 3/8 inch off the end of one axle, so yes you can reuse your 35 Spline axles in the Dana 60 with the 35 spline Strange, Dutchmen, Yukon and many other spools Make sure and check for end play, don't let the axles butt in the center The exception might be the Mark Williams 35 spline spool with thier different axle and spool teeth angle, 30 degree versus maybe 45 degree angles, not sure which one is which

Yes you can, you have to put 8 3/4 ends on the dana. Brakes will work too.

After that, will I need to brace the housing or special welding to the Dana ?

NO Not even close, sorry But your 35 spline axles (brakes and brake drums will fit on the new ends also) in most 35 spline spools BTW, make sure and mark your axles(right and left) when you take them out of the 8 3/4 and put them in the new cut down Dana 60 on the same side thay came out of so you don't try and run them backwards to what they've been run already

I believe we had to change spools..

But there is no need to backbrace the dana
