Welcome to the forums! Love the coupe! I am restoring a 72 Coupe myself!
Hope you enjoy it here!
It appears Iceland is well represented when it comes to the "big bodied mustangs."
Very nice car - - I particularly like the stance. Are you running original suspension and what size are the wheels and tires?
Welcome to the site!
GREAT selection on the tire sizes - - that probably accounts for the stance.
With that "high" gear, I would assume you do quite a bit of "highway-type" driving?
Again, welcome to the site!
Love the coupe!
Hi and Welcome the coupe look good well done.
The Bronco and Mustang for that period share the same carrier assembly. They are totally interchangeable between the same splines (28 or 31) axles. Generally speaking, they both had the 28 spline 9" rear.
From the factory, the carrier assembly had a metal tag on it that pretty much tells one exactly what ratio it has. It also had a three (3) letter code, probably WFC or WFD (most common 9" 28 spline carriers).
If the tag is missing, you can figure out the rear gear ratio by:
1. Jacking up the rear end
2. Mark a tire with chalk at the 12 o'clock position
3. Mark the drive shaft with the chalk with a horizontal line
4. Rotate the rear tire one full revolution while having some one watch the driveshaft to see how many times it goes around. The number of times the drive shaft rotates determining the axle ratio. I. E., if it rotates 2 1/2 times, it is a 2:50 ratio.
Note: This is if you have a locker or other limited slip axles. If you have an "Open" rear, you will multiply the rotation of the drive shaft by 2, i.e. if it rotates 1 1/4 times that would be a 2:50 ratio.
Again, I would not be concerned about the rear being from a Bronco as they really use the same rearend (Carrier assembly) as the mustang (and many other Ford/Lincoln/Mercury products) for a given application.
Hope this helps!
