im gonna go ahead and say he lied, find out what gears it has for sure before you buy it. IT may have 3.55's but it shouldnt be stock.

I think I might stay away from this one. There is another one for sale that i can get for $10 more- 260. unless somebody comes in and says that 3.55 was defintely an option.

Maybe in the 4 banger but certainly not in the V8

My '89 GT came stock with a 3.08, but I don't know of a Mustang with anything lower than that stock.

I had the "Z" Code 3.08:1 gears in my 1992, but now have 3.73:1

The 3.08 was actually a step up from the 2.73:1 that most got.

actually he said this was an order option. meaning that the person who got the 3.55 option had to order this through ford when they bought the car.

In that case I might go for it. I mean if it's not worn out, a gear is a gear.

you can check to make sure they are really 3:55's. i got ripped off on a rear that was supposed to have 3:73's, turned out they were freakin 2:73's. if the rear is already out, take a piece of chalk (or something alike) and put a line on the top of the circle the driveshaft bolts to. then spin one of the wheels one full rotation and count how many times the pinion spins. if it's about 3 and 1/2 times then they are 3:55's. if a little more than 3 1/2 then they're 3:73's and so on.





The previous term, replaced with that in bold, was removed as it was innappropriate- Mngmt

The highest gear available was a 3.27 in the 93 cobras. No 3.55's were stock...

Just look at the problems people have with their speedometer when they put 3.55's in. There is no exact speedo gear for it without changing the drive gear in the tranny...and ford didn't make tranny's with different drive gears........

93's came with 3.08's

The 3.27 was also available for AOD equipped stangs. And what do you mean by: "and ford didn't make tranny's with different drive gears.." I plan on changing my drive gear to a 6 or 7 tooth from the 8 tooth whenever I do a clutch for my car, so I'm not following you at all on the above statement. And they did have different drive gears for different year model t5's that can interchange. 87-89 had a 7 tooth, 90+ had a 8 tooth. Thats why 89 and older and run 3.73s with a 21 tooth and the 90+ had to run the 23 tooth. Yeah your right there is no exact speedo gear, but the only way you could get an exact mph is if you had an adjustable unit to compensate for different tire heights and gear ratios, etc. Maybe I just misunderstood you, but thats they way it sounded to me.
