Hey guys, the sticker on my door is unreadable, and I could not find a tag on my axle. On the build sheet under rear axle tag number is printed out 014A. It is defininetly an open axle and I am sure it is original. My service manual was no help. Does anyone know what ratio it would be?

If it is bone stock, no sway bar or heavy duty stuff, I would guess 2.73. I think that's what most of them have. But I have been wrong before!89 CV LX 225/60 x 16 tires, CC819 rear springs, Front & rear sway bar, trans & PS cooler from 90 cop car. KYB shocks, F-150 on rear. Dual Exhaust w/ H pipe. Dark brown door panels, carpet, steering wheel, trim parts from a 87 Mer GM. Power front buckets from 96 Jeep Cherokee. LED'S front & rear. 3G Alt from a 97 Taurus wagon 3.0. Electric fan. Rear axle from a 97 PI 3.27 with disk brakes. Headlight relays.Comment

When I went junkyard shopping for my axle I found that almost all boxes had a 3.08 unless it was set up with the towing package, then 3.55's. 3.27's were rare, as were 2.73's. I'd love to compare build sheets wid youse, but I AIN'T GOT ONE!!'84 Grand Marquis

ps. It's pretty easy to calculate your rear end gear. Jack up one wheel. Slide underneath and put a piece of masking tape on the rear u-joint in such a way that you can tell when the drive shaft makes one revolution. Now, put the car in neutral (block a front tire!!!) and spin the tire off the ground by hand 5 times while counting how many times the driveshaft rotates. Almost 31 times? 3.08. Almost 33 times? 3.27. A little over 27 times? 2.73.
You don' need no stinkin' tag!!!!!'84 Grand Marquis

I've got 2.73 open in both of my panthers. Probably the "flat land" setup since I'm in Texas and both cars were originally shipped to Texas for sale as far as I can tell.

UPDATE duh
So I guess I need new reading glasses worse than I thought! I went back to the '86 service manual and looked through all the rear axle section and found 2 charts. First is for open diff
ID TAG Ratio
039A 2.73
422E 3.08
033A 3.08
014A 3.27
012A 2.73
014A 3.08
Cool my 014A could be either a 3.08 OR a 3.27!!!!
Locking diff
ID TAG Ratio
013A 2.73
015A 3.08
034A 3.08
201A 2.73
203F 3.08
205F 3.27
421E 3.27
423E 3.08
I can understand having more than one code for a specific ratio, but having the same code for 2 different ratios? dang engineers I am back to the drawing board.

My Vic doesnt have any excessive options and I have a 3.27 open. I am pretty sure the buyer of the car could specify what gearing they wanted.-2004 Crown Victoria Police Interceptor - Daily Driver - 17" Bullitt's, 235/55/17 Goodyear Eagles, Ex-NH State Police, best 1/4 mile time; 15.3 @ 90 mph

My car has the plain jane 3.08 open rear end - If I found another Panther rear end, would it be worth it to swap it out for either a) 3.08 locking diff or b) an open diff with higher gears?sigpic
