    Where To Find The Nine Inch Rear Axle

    1967-1973 medium and big block Mustangs and Cougars 1966-1971 Fairlanes, Torinos, Montegos, Comets, and other Ford intermediates with big blocks.
    1957-1959 V8 Fords and Mercurys
    1977-1981 Lincoln Versailles & Trucks
    Types Of Nine Inch Axle Housings

    1967-1973 Mustang/Cougar - light duty, thinnest housing material, small axle bearings, 28 and 31 splines.
    1957-1968 passenger car and 1/2 ton truck - medium duty, stronger than Mustang type, 28 and 31 splines.
    Ranchero/Torino - heavy duty thick wall housing, 3.25 inch diameter axle tubes with flat tops.
    1969-1977 Galaxies (coils), Lincolns (coils), and late pickups (leaf)- 3.25 inch diameter all the way to the backing plate, coil housings have upper control arm mount
    How To Recognize Nine Inch Housing Centers

    1957 - no dimples, flat center band up the center of the rear cover, bottom drain plug.
    1958-1959 - two dimples on back of housing, flat center band, some had drain holes.
    1960-1967 - two dimples, flat center band, oil level hole in back cover.
    1963-1977 Lincoln, LTD, Thunderbirds had 9.375 inch centers, housings were cut away at the gasket surface for ring gear clearance, one curved rib at the front top portion of differential, strong but no gears.
    Tip On Shortening Nine Inch Axles

    1972 and earlier 31 spline axles have the ability to be shortened.
    28 spline axles are tapered and cannot be shortened and re-splined.
    1973 and later cars have a 5-on-5 bolt circle and the axles cannot be shortened.
    1967-1973 Mustang axles can be identified by wheel flange:
    Oval hole = 28 splines.
    Two large holes and counter-sunk center = 31 splines.

    Where can I find a diagram that shows where to measure to and from?
    The measurement I get on my axle assy on my 65 F100 is 57" from end to end.

    Found it, thank you Hemmings was the ticket.
  12. Always measure from wheel mount surface to wheel mount surface. You don't fit your wheels to the backing plate or the spring mounts....

  13. Sorry, standard of the salvage industry is backing plate to backing plate......learned the hard way after making a 5 hour round trip to look at a 65" rear end....turned out to be a 60".

    from Quincy, IL

    Is 65" a typo.........did you mean 55"? A 65" backing plate to backing plate rear end would be closer to 70".

    Hemmings says on a '65 F100 the dimension is 57", which mine is from
    end to end to the bare flange with nothing installed on the housing.

    It isn't out here. All of the yards I deal with quote wms-to-wms.

  17. I have been on the phone, text and e-mail with numerous (over 10) yards in Florida and EVERYONE of them quoted me backing plate to backing plate measurement........

  19. Flange to flange is the proper way to measure a rear, the Gimp know and now so does everyone else. ;)
  20. I've had a few of the 59-60 Thunderbird housings and they are the same as the 58-62 or maybe 1/2 " narrower than Ford car housings. 2 Dimples.
    Difference is 58 T-Bird was a coil spring car (initially designed to be air bagged but never happened) and the 59-60 have narrower spring perch mounts.
    All these sites neglect the T-Bird for some reason. From the housing flange measurement add 6" overall to be very close. Currently fifteen 9" rear axles in my shop.

  23. Just trying to find a rear end for my 63 T-Bird kustom.....narrowed 16".
    I have talked to yards in CA and AZ, both measured the rears by the backing plate. AND they both told me that the T-Bird rears were very different as the brake drums are very wide. Just saw one yesterday, the drums look like they came off a 1 ton truck.
  24. All of the useful charts of rear end widths I've ever seen are wheel mount surface to wheel mount surface. The backing plate to backing plate by junk yards is because they are too lazy to take the wheels off and give you a meaningful dimension. At the end of the day you need to know the rest of the width. Your results may vary.
  25. The reason you measure flange to flange is that gives you a mounting place for your wheels, you can add about 3/32 to each side for brake drums. The reason you can't measure a rear backing plate to backing plate is that the backing plates have different offsets to allow for drum width.

    A '58 Ford wagon for instance is 58" flange to flange, if it had 2" drums or 1.5" inch drums it would still be 58". Maybe the wagon has 2" drums and the car has 1.5" inch drums, they use the same rear end. The measurement backing plate to backing plate is going to be 1/2" difference for the same rear.

    Now onto your dilemma, if your custom rear is narrowed 16" that tells me that you have a pro street T bird and not a custom for starters not that I really care. But you are not likely going to call around and find one in a wrecking yard, you are going to have to get a rear and have it cut down or cut it down yourself in which case width makes no difference at all. You snag a rear and set it up to fit.

    Note: the drum width is nominal just for the sake of argument.

    Commonality does not equal correctness.

    If everyone repeat the same mistake, it does not elevate it to the level of truth.
    Atwater Mike and lothiandon1940 like this.
  27. I talked to a yard today, the reason they all measure backing plate to backing plate is that they sometimes sell just the housings, cannot measure axle flanges if they are not there. I am also trying to find a disclosure on one of the charts that the measurements are backing plate to backing plate and that some axles extend out farther than others.
    I can understand that a consumer would want to know axle to axle distance....
    cannot see it as a mistake if over 10 places I have contacted give me the same measurement....
  28. The standout should be the same on a 9" ford, so if they are measuring the from the bearing cup flange to the bearing cup flange you can have an accurate measurement of the rear end. Where the variance comes in is that backing plates are offset to allow for brake show width, some backing plates are offset more then others. What makes it wrong in our world is that variance. We need to know where the wheels are going to land not where the backing plate is going to land.

    As for usage making it right consider this, she hit huh leeeg ooon da doh. Gets used a lot, has been for years and is still not correct.
  29. In my business its not a firewall...its a dashboard support panel.....
    Because if it was a firewall then it would not allow fire to enter the passenger compartment......

    Most of the backing plates I have encountered are not offset, its the offset of the axle and drum from the backing plate, because of difference in brake shoe width... a 1 7/8" shoe compared to a 2 1/2" is not made up by offsetting the backing plate......
