Hi

Personally, if you were on a budget, and just didn't have the funds to install an 8" rear end at this time, I think you could live with the 7.5 rear for the time being. The car is very light and would be more likely to spin the tires. besides, when installing an 8" with a 5 lugs, then you'll be lead to changing out all your suspension and probably do a drum to disc conversion. but you will probably be having to upgrade your front springs for the additional weight of the 8 cylinder motor.

BTW, your car looks great, the 6 cylinder also looks great! Why are you wanting to go to an 8 cylinder?

I did the conversion years ago. For budget reasons I kept the 7.5 rear and it did fine. If you don't have enough traction for the tires to hook, the rear end won't break. If you don't have posi gears, you don't have enough traction for the tires to hook. I later, as I got the money, put in a 9" rear, new suspension, and a disk brake conversion all the way around to go 5 lug.

am going with a 9" diff. What about the front? have been told the V8 stub axles limit your steering, only giving u half lock?? but the 6 are two weak? kinda confused because i cant see why ford would bring out a car with only half its potential steering cirlce!

Thanks Dne'. Im only 19 and in Australia (NSW) drivers under the age of 20 cant drive a V8 so im getting the car ready for when i can :)

alrighty then!

Okee dokee~ if you're going to install a 9" rear, then you may as well start looking for what you want to do with the front(switching from 4 lug to 5 lug, disc brakes, steering and suspension?). How much can you afford to do? What do you want to do? you could do steering with manual steering or factory power steering, or rack n pinion($). Disc brake conversion kits(power or manual brakes), Doing all this you may as well install new springs all the way around! Just to get you thinking!:bigthumbsup Do your research and see how close you can get to how much time and money it's going to cost you! Know exactly what you want before putting any money out:gringreen!

so far this is what im thinking ill need/do . . .

front - will be converted to Discs (5 stud and boosted), new springs and will need new tie rod ends. Im pretty sure i can use the same stub axles and control arms tho.

rear - 9' diff (32spline axles, disc brakes), theres a local guy who can reset the springs making them stiffer or i can buy a new set for around AU$450.

what do use reckon? more ? less? anythen i've missed ?

Thanks andrewmp6, have actualy read that article. its a good site ey! especialy there C4 rebuild!

cheers. Im new to this so can use all the help i can get! :) :scratchchin

Or you could find a aus or nz mustang forum and see if any of the early fords you have there you can use to swap the spindles to disc brakes.Its a long shot but might work since you all early falcon is the same thing ours was.
