    Like the title states, I'm trying to find the best way to mount this Ford 9" to the back of my stock frame.

    The front is an original 28 front end with no drop at all. This car will be pretty high. Plans are a Pontiac 400 for an engine and this 9" in the back. I found an original banjo rear end with the suspension still on it. I've seen people use the original rear suspension with something like this:

    http://www.speedwaymotors.com/Trans...gn=CSEGOOGLE&gclid=CKurzv6Wis8CFQQbaQodqm4KhQ

    But I see my rear end is set up for a coil over setup. Would it be worth chasing that style or just chop it all off and go with a more period correct. This will be a tall car so I would think people would see the suspension pretty easily.

    Next question, with the front end sitting at it's normal height will I have to chop the frame for this? I regret that i don't have a modern picture of it sitting with the suspension bolted up to the front.

    Pics below.

    Forget all those factory brackets and miss. On the rear, cut all that off and mount an A or T spring above and some sort of ladder bar set up.

    Have you checked the width on that compared to your body/frame? The coil spring rears were usually under full size Fords and might have the wheels really hanging out there.

    yeah It probably was. Maybe an LTD. There is a local guy who would take this 9" and $100 for a smaller one from a bronco with 5 1/2 bolt pattern I might give him a call and see if he still has it.

  6. Go get the bronco rear!! that is the best one width wise for that A. The one you have is gonna be to wide and make the wheels stick out something awful.

    So with either the bronco or this galaxie/ltd rear end I should do the original suspension setup?

    Any thoughts if i'll have to chop the frame with the high front end the way it is? I'm lazy so I don't really want to chop the frame unless I have to.

    By chopping the frame do you mean Zing it? If your front suspension is stock besides a few inches lower due to heavier moter then set up the rear with stock style spring or even an T spring and should work out, just depends on how you want it to sit. You said you want it to sit kinda high so no need for Zing the frame at all.

    If the Bronco rear is the early narrower one your rear and 100 bucks is the deal of the week.

    On the rear you have if it wasn't way too wide The first thing 99.9 % of us would do is get the torch and grinder out and clean the scabs off and start with a clean bare housing and go from there.

    '32 in the picture has a stock 32 spring on a Speedway spring perch kit. Stock front spring with reversed eyes and somewhat flattened cross member. Sits pretty low, I thought. Home made ladder bars. I think something more like original wish bones might have been better. 05_2421.JPG

    400 Pontiac is circa 1966 and up, coils ARE period correct. Lots of hot rods from that era were built with rear coil springs, Corvair springs were especially popular.
    Or do you mean "traditional"? The two are different.

    Huh. I have a parts corvair from my '66 build. That's where I was going to plunder my steering box, I didn't know I could maybe steal the springs as well.

    Alright, I got off the phone with the guy who has the 9". At this point I think I'll be getting a different rear end and I'll be doing the tranverse spring in the rear.

    I thought about making a new post but I didn't want to be that guy with two threads at the top of the forum. I could use some advice on which direction to go;

    9" that he says is 58" that came from a 50s ford. 5 - 4 1/2 bolt pattern.
    Couple of 8" that are between 58" - 60" from older fairlanes on a 5 - 4 1/2 bolt pattern
    9" that he says is 60-61" from a 1960s pickup that is 5 - 5 1/2 bolt pattern.
    Skinny Dana 44 in the 58" range that has 4.10 gears and "would be a lot cheaper"

    He doesn't have a bronco rear end anymore, I did find one locally but that guy is asking $500 firm.

    I also have a 1968 Ranchero at the farm I could pillage the rear end from but reading says that one is 61.25", so a bit wide...

    Thanks!

    Unless your going to run big sticky tires i would nab that 8" and save some unsprung weight.
     
  15. In my opinion, you should look for a rearend that is about 58" wide whether it is a 9" or an 8". Get the right width, an 8" would hold up unless you are going to race or treat it rough. A 57-58 Ford rearend is the perfect width 9" if thats what he has. But a 67-68 Mustang 8" is a good width also. Anything from the 60s full size cars is going to be too wide.

    I plan to get a bit rowdy with this car so I'd like the 9" over the 8".

    Sooo which one to get?

    58" Ford 9" - $300
    58" Ford 8" - $100
    58" Dana 44 - $50

    He said he would also take my rear end for a $50 trade.

  17. You aren't going to hurt an 8" in that car. I have one under my Falcon that is an autocross car with sticky tires and a manual trans ~ it is heavier than your car, and hooks up better than yours will and I haven't broken it. I also had one in my 31 coupe with a 350 Chevy and some pretty big tires, with a factory limited slip, and didn't break that one either.
     
  18. That first rear end you showed isn't set up for "Coil Overs" either - it is set up for Coil Springs - Big difference.

    The '57 Ford Wagon will fit just right, & use Posies semi elipictical kit for good stable cruising.

    That Bronco 9" has the pumpkin centered along with being much narrower than your present rear. Big axle flanges and early Ford bolt pattern make this a no brainer. Go for it ! P.S. The rearend builders in San Antonio echo what hotroddon says, that an 8" will handle 400 hp plus a bit.

    He doesn't have it anymore or he didn't have it to begin with.

    His 8" rear end came out of a 63 Galaxie and from what I can read that width will work and he's only asking $100.

    I'd like to get his 9" but I can't convince the wife it's worth the extra $200
