On my door seal under where it has a bunch of stuff it says AXLE and then under that it has 86 - am I looking in the right place?
The list reads:

42 3.45
44 3.73
47 4.10
72 Regular 2200lbs 3.08
74 Regular 2200lbs 3.45
82 Regular 2700lbs 3.08
84 Regular 2700lbs 3.45
85 Regular 2750lbs 3.55
86 Regular 2700lbs 3.73
87 Regular 2700lbs 4.10
91 3.27
92 3.08
95 3.55
96 Regular 3200lbs 3.73
F4 Limited Slip 2700lbs 3.45
F5 Limited Slip 2750lbs 3.55
F6 Limited Slip 2700lbs 3.73
F7 Limited Slip 2700lbs 4.10
K6 Limited Slip 3200lbs 4.10
D2 3.45
D4 3.73
D7 4.10
R5 3.55
R6 3.73


So I have: 86 Regular 2700lbs 3.73


Am I right?

Yes, yes you are... I have an 86 as well and that is your info

86 = 3.73 non l/s

That's what i have :)

thanks guys..

I think I'm going to stick with the 3.73's - maybe some L/S or trackson bars are in order..hurmmm..
