I am thinking about looking for an old granada for the disk break(5lug) setup for my 63 falcon. Will a granada rear end fit under the falcon as it will help determine how much a granada would be worth to me for parts. I want a 5 bolt lug setup as I hate 4bolts

REAR SUSPENSION:

The following is a general list of rear ends and their dimensions to help narrow the search for a possible candidate to replace the torque tube rear end or just get a better set of gears for highway driving.

Advance Design Trucks seem to be using rear ends with widths ranging from 58"- 62". I'm not sure of the Task Force width ranges at this time.

Where to Find the Nine Inch Rear Axle

1967-1973 medium and big block Mustangs and Cougars

1966-1971 Fairlanes, Torino’s, Montego’s, Comets, and other Ford intermediates with big blocks.
1957-1959 V8 Fords and Mercury’s

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.
 
definately needs a sticky... i dont know how many times i search for this info,lol.
 
I just measured the WER code axle from a '78 Granada yesterday;

43" between the centers of the perches
45" between the outer edges of the perches
50" from backing plate to backing plate
58" between wheel mounting surfaces

Hope that helps... the axle I have is for sale, I think I posted it in the classifieds. (y)
 
Many years ago the Granada disc brake 9" was the ticket for Mustangs because so few cars had rear discs that would easily swap.

But now the Granada disc rear is kind of obsolete. The calipers, rotors, pads are all harder to come by and expensive. The e-brake is difficult to hook up. The stock gearing was usually some very tall freeway ratio with an open center section.

These days, with all the aftermarket support out there it's easier, cheaper, and you get better brakes by either buying a kit for an 8" or 9" rear. Another very viable option is adapting a different disc rear from something like a Ranger or Explorer.

And for the Falcon owners, an inexpensive, narrow rear end option with discs, posi, and a wides selection of gears is the Chevy S10 7.5" or 8.5". The 2wd rear is 54.25" wide and will give a bit of extra room for wider wheels. Just redrill for the Ford pattern or use Chevy pattern wheels.
