Ford 9in rear axels. googal ford 9in rear axels,the site has all the info you will ever need. they say 57-59 ranchero and 65-67 mustang hps ar the same width 57,25. giv it a try,ther ar other sources listed. cliff 57ranchero

I was at the Ballarat swap meet today and I saw one the same and they said it was a zepher diff. And some of these were found in ford cars to.

nearly bought a 9", yet many other goodies.

I also found a what I think is a Dana 44 which was out of a Mainline ute. I can get it for $75, Should I buy it and keep as spare? or fit as runner?He thinks it may be a 3.5:1 ratio.

All Aussie Mainline utes were 4.11:1 as far as i know.

Strong diff, aussie drag racers used to use them before 9"ers became available.


I have a 3.55:1 out of a 53 sedan delivery in my 52 Mainline with 302w and AOD.

Manual OHV mainlines, 4.09 ; 1, Auto mainlines 3;54. The 4.09 is usually stamped on RH diff tube looking from the rear. The 3.54 is usually stamped on cast web running to tube area. Allow variances for my fadeing memory.

He mentioned it may have been a 3.55:1I think for $75 I should just buy it. I will check the tubes and casting to see.

So it is a DANA 44 ?

Yep

The Lincoln Versailes disc brake rear end has the same width, center pin to center pin, as my 57 and 58 rancheros. Not sure what the t-bird width is, hope this helps





thanks, Mark

So the diff in the bird at the moment looks to be a shoebox 49-51 merc??The axles are a 17 spline, yet thick shaft similar to 28 spline 9" ????
