Thanks a lot to everyone of you.

The seller told me today that 51 is not from flansch to flansch but from outside the brake drum from outside the brake drum.

So I can forget about it I think : (

That's what I understood you to say in your first post. I was thinking that it was 51 inches total, not flange to flange. That is why I thought it was too narrrow for what you needed. If it had been the width of the housing then you could have added 5 inches to that for axle hang out plus about 1/4 inch for brake drum thickness, which would have been pretty close for what you wanted.

I quickly measured the rear end in my Camaro again and it's about 46 1/2 total with 14 inch wide wheels and about 6 inch back spacing. The brake rotors add about 1/2 inch to the width.

Thanks tough for the info : )

I saw a 9" housing on eBay but it is a floating version and I dont know what all I need to complete it, it does not have any flanges at the ends.

Does anyone know more about that type of 9"ers?

51" Wide 9" Rearend In A 68 Impala Pro Tourer??? 1 way is the Right way

I hate to see you spinning your wheels.
Big Gear Head had it right - you must select your wheels before you know how wide the rear end must be. I'VE BEEN THERE - I installed a Nova 10-bolt because it was fairly narrow and common (read cheap) and then went shopping for a wheel that I determined the width of via cardboard template. The cost of the wheel went through the roof to get custom made!! Plus, it was NOT my favourite pick/brand!
If you are referring to the "9 inch ford floater rearend new 78-87 g-body malibu" on eBay from Quick Performance, the ad states it is a 60" and that they have 58 & 61s also. It is made to fit the GM Malibu body types '78 to '87. It is a GM/Ford hybrid housing - very strong, probably good to 1,000HP. A reg GM 8.25" 10 bolt is good for about 400HP, a 12 bolt for 500HP - all dependent on tire size/type.
FIND OUT WHAT WIDTH YOU NEED, USING THE WHEELS YOU CAN GET! This is not difficult. Any other method is a cart in front of the horse.

Strange that there is only one way to get a hot rodders challenge right. In fact there are many ways to skin a cat as long as you get the cat skinned. Some are just better or easier than others, but that does not make them necessarily right or wrong. Case in point: hannes has a fixed wheel well opening: he has the possibilities of a narrowed 9" Ford housing that is 51" wide from wheel mounting surface to wheel mounting surface. He can do simple math to determine the back spacing he needs on a wheel to give him the wheel well clearance on the both the out side and inside of the tire of choice. Once this is done, then he has to determine if such wheel and tire combination is available to fit. We can talk rear end widths, custom made wheels for days and what the ideal way of skinning the mix and matching parts until our fingers are worn out. Our job is to see if what we have to work with will work, especially when you are on another continent that is not into the hot rodding scene like the good ole USA. If he finds out there is no way he can use this pre-narrowed rear end, then he can get his wheels and tires of choice to determine what width and where to located the 3rd member, assuming he has some one that can do this in his country.
