RE: Rear end

Axle Code
Conventional....Lock.......Rear Axle Ratio
G....................H...........2.26
B....................C...........2.47
8....................M...........2.73
7.....................- ..........3.07
Y....................Z...........3.08
4.....................D..........3.42
F.....................R.......... 3.45
5.....................E...........3.27
6.....................W..........3.73
2.....................K...........3.55
A.....................-...........3.63
J......................-...........3.85

This is probably a generic rear-ratio chart for Ford's rear-wheel drive cars. Just because a code appears on this chart doesn't mean it was necessarily available in the Mustang.

RE: Rear end

heres the mustang gear ratios

M = 2.73:1 w/ Traction-Lok
Z = 3.08:1 w/ Traction-Lok
E = 3.27:1 w/ Traction-Lok
R = 3.45:1 w/ Traction-Lok (GT Turbo only)

GT Turbo = SVO

RE: Rear end

can do it in an afternoon, but you really gotta know what you are doing, backlash has to be set properly, as well as the contact pattern between the two gears.

RE: Rear end

no reason for a sticky w/ that whole chart.

m=2.73
z=3.08
e=3.27 and only av. in aod's

'86 + are 8.8's

total cost should be about $500-$600 gear + labor
