What is the first year for an 8.8" rear in a Mustang? ...

I was pretty sure that 86 was the first year..I'm not saying that late 85's dont have them, but every V8 in 86 had an 8.8" I know that for sure...What's the correct answer?...

This link says that 85's dont have 8.8's

just 'cause it comes up a lot, the '84-86 SVO's had a 7.5" rear, nice ~50 lbs. weight savings at the stock power level...

For some more proof, I called the local parts stores for a differential cover gasket.......I got some Felpro #...For '85 its RDS-55081..For an '86+ its RDS-55341...

This is just more prof that 86 have 8.8's and '85 dont!..

Although visually, the 1986 Mustang GT was nearly identical to the 1985 GT, under the hood was a completely different story....Also big news was the 8.8-inch rear axle, a big improvement over the 7.5-inch ring gear. Other upgrades included a clutch enlarged from 10” to 10.5” and new viscous (fluid-filled) motor mounts. Axle ratios carried over from 1985.
