rear end questions
 

i have a 9" housing out of a torino that i was concidering under my 69 camaro. I have a few issues with the 9" though. First, all i have is the housing and the wrong lug pattern axles, second, i have a set of 4th gen camaro rear brakes i want to use and im not sure what its going to take to install them on the 9" backing plate wise, third its going to be pretty pricey to build this thing up unless i can find a fairly nice used 3rd member and finally the rear end is the correct width for factory wheels and tires but im running zo6 wheels which require spacers

the other option i was concidering was a 12bolt out of a 73-87 chevy pick up. and for a few reasons. 1. i can buy a fairly built one off my rock crawler buddies with gears and all for around 500 and just get axles with the right bolt patter for 3 or 400. 2. its going to be the right width, shich means no spacers and 3. im under the impression my brakes are going to "bolt on".
I have read some bad things bout the truck 12bolts though as far as strength goes. i plan on reaching the 500hp mark and only running street tires in an auto-x manner. no drag racing.

so what do you guys think.. i mean id love to just throw down 2600 and be done but id like to buy control arms and such. what do you think the best route for me is going to be?

Why not just buy a package from one of the axle manufactures.That way you would have the correct everything.Stan

well i dont want to spend 2500 if i dont have to. my car could use alot of other goodies...

Before I considered a truck 12-bolt, I'd look at the 65" wide, fishmouth housing, Ford 9" from a 1977-1983 F150 or full-size Bronco with 31-spline axles and a Trac-Loc. I can get these all day from yards for $100-$250 around here in Oregon. Even though you'd need to swap or modify the axles, the gear ratio will more than likely be 3.50 or 4.11 and it's already set up for 31-spline axles. New GM/Ford hybrid ends can be had for less than $100 but will need to be installed on the housing...another $100-$150 or so. Just make sure you use the "flush mount" ends so that you won't need to run a spacer with your LS1 backing plates. Shock mounts and spring pads could be done at the same time as well.

The E150 vans of the same era (up to '86 IIRC) had an even wider version of the 9" at 68" WMS-WMS if that's needed. A lot of the off-road guys running full-width Dana 60's up front pair those up with the van 9" in the rear to match track width and maintain the smaller 5-lug patterns versus converting to 8-lug in the rear.

8.5!
 

build a 72-78 nova 8.5" rear end the 75-78 behind a v8 are 8.5" posis are available as are gears or i can build you one - stronger than that truck 12 bolt-pinion diameter is smaller and i have seen these sheer off - i wouldnt wast my time or money on a 9" or that truck 12 bolt- the nova is pretty much a bolt in - watch your springs most nova's are multileaf and you may need to shorten your drive shaft - im local in Lewisville for you too
