Building a junkyard 9" compared to 8.8

I never even thought to just take measurements and use an angle finder.This is sounding easier and easier. You had said the torque arm was off by an inch,I know its not going to cause any problems if someone were using a stock mounting set up with a bushing,but could see it causing a problem for someone that has a crossmember mount,especialy one that was previously installed.This part I would jig.This is way cool. Thanks for the info and pics as you went along.

Here are some pictures of it in the car and how the axels work.
The measurements on my axels where passenger side 30 9/16 to backing plate flange, drivers side was 28 1/8. That was all Quick Performance needed to make them, they already know what the brake backspacing is. When measureing make sure your tape is bottomed out on the pin that runs threw the carrier.
They forgot to send me the u bolts that hold the u joint into the yoke. Thats why its not bolted up yet. They are coming with my axels.

I put my spare hacked up 10 bolt on my little utility trailor and I will be taking it along with my 9" housing when I go to have it narrowed just for verrification purpouses.

Great job! I started the same project around the same time you did. I went through quick performance for everything. great deals
i was lost on what to do for the bearings but thanks to your thread im confident in finish er now. I just have to order my axles also then im golden!
I just felt like adding a backbrace onto mine...
figured i would post some pics also, hope ya dont mind...
didnt put sway bar on yet... the spohn sway bar mounts extended them down a little to help clear the housing
good luck!

Looks good! I thought about the back brace but I dont think I will ever be able to hurt the housing I have. If I ever start making crazy power I might pull it out and weld one on. What did your housing come out of? Also are you using a stock cast center or is it nodular iron. I was tols the stock cast iron wont hold much power.

It is the stock casting center... im taking a big chance for sure, but hopefully the daytona pinion support and bearing will do it some justice

its defiantly tough to tell in the pic but they measure out the same
Thanks man, I defiantly had to take it slow on welding that back brace on, it defiantly warped the housing about 1/16 of an inch... thats y i put the axle flanges on last so it will true it up to the carrier bearings.

I am not trying to knock the stock cast center, I am just trying to see what they will handle. I still have mine and might set it up with another gear. I work with a guy that has a full blown drag car, thirdgen camaro, with a 9 in it. He said they blew the pinion out of a stock cast center. He said the driveshaft looked like a pretzel with the pinion hanging off the end of it. I guess the cast housing is kind on thin in the bottom of the pinion area and are prone to crack.

When I put my housing in the lathe and spun it up it had way more run out than 1/16 of an inch. By no means were these things straight from the factory. I dont think you hurt anything. These axels are running on ball bearings out on the ends so you have some room.

I do like to build things and I will build mine, but man! I was just adding things up the way I want to build mine and its only like maybe $250-300 less then just buying it. kinda sucks. Not as cheap as i thought it would be.

I got my axels today......and one of them is too short....
Man this crap always seems to happen to me. Anyway, I thought I was getting Quick Performance axels. Turns out I got Moser axels and one of them is about an inch too short. My measurements were right 30 9/16 passenger and 28 1/8 driver. The driver side was right and as already together. The passenger side is the one that is wrong it measures 29 1/2 instead of 30 9/16. I called QP and they said the order they sent to Moser shows 30 9/16 and 28 1/8 so they are going to have to work it out. I think I know what they did wrong
This is the landing that the bearing presses against and is where the axel should be measured from. If I measure the axel from here it comes out about an inch to short.
If you measure from the next landing down the axel measures what it should 30 9/16. So looks like Moser f'd up. Figures....

Called QP back today and they said that Moser is sending me the right axel. They also said that they admitted to the screw up with out a fight which normally does not happen. I asked how often this happens and they said 1 or 2 times a year......

Thanks, I am not in any hurry. The weather is crappy so I cant drive it anyway. I should have it mid next week.
I am going to change the tranny fluid while I have it in air. I dont like the way it shifts with the Mobil 1 in there.
Its a shame I have spent all this money on these rear ends becasue I would really like to get some headers and a Y pipie on there this winter.
