Ive been looking around for some axles for my nine inch but not sure of what it came out of. its about 56 inches from flange to flange so it will finally fit in bettween my fenders. i would like to buy a OEM type axle nothing crazy. i read in the articles above you could use '77-'79 T-bird, Cougar, LTD II, Ranchero, and '73-up Torinos left side (driver's side) axle but where do they sell them besides the junk yard.

If the pumpkin is in the center of the axle (equal length axle shafts) it's likely out of a truck, unequal length likely out of a passenger car. There is plenty of ID info on the internet, you'll need to know if 28 or 31 spline, large or small bearing, bolt pattern desired. Even custom axles are not horribly expensive if you want a different bolt pattern or special length.

 

Hopefully you have the original nine inch truck backing plates, brake assemblies, and axle retainer plates because you will need them to use with the passenger car axles...

 

yeah i do i had another 9 inch but it was alittle to wide.
