hi everyone,
I have a random question. I have a ford 9 inch 28 spline rear axle i believe from 67 bronco, i need a 3rd member for this. One of my buddies who lives rather far away has a 3rd member from a 91 cobra, does anyone know if it will fit/ work? also what is the gear ratio/ is it posi? sorry for all the question i would rather not make the drive to test fit because its pretty far.
this is for my 30 model A so it might be a little off topic. ill post a pic for you guys though

actually, there's was no 91 cobra.

and if it's a gt or lx, it would have an 8.8, not a 9 in.
