There is a 9" for sale near where I am located out of a 71 Mach 1. I was just wondering if it would fit in a 67 coupe? or would you have to do some mods? Thanks

 

There is a chart a t the bottom of this page http://www.maliburacing.com/ford_9_i..._nine_inch.htm
according to the chart the 71-1-3 is one inch wider

 

If you already have the 9" axle housing...the pumpkin will drop right in.

 

I have a 8" so I would have to get the whole housing. From what I can tell it would work I would just have to get different rims in the back to accomidate for the etra inch? Also whats a decent price for a 9"? I dont really know what they go for and dont want to be ripped off. Thanks alot

 

The location of the leaf spring perch may also be different, so be careful.

 

That perch thing is true but dang it's only and inch wider. If the perch is only and inch difference that is only 1/2 inch each side. I have cheated the springs out 1/2 inch!
