Yea, okay, I won't go there on a family forum. I have always heard the Ford 9" rear end is the best ever made. But, how do I tell an 8'' from a 9" rear end, and what's the difference between the two mechanically.
Look for two dimples on the rear (the side you can see from the back of the car) of the pumpkin. Also, look for lots of reenforcing ribs cast into the front of the pumpkin where the drive shaft attaches. Most of the 8" units (pre-67') only had three puny ribs. The 67' and up 8" units have more ribbing, but less than a 9". Don't forget that while the 9" is the undisputed strength king, it comes at a price. The price is unsprung weight. I have heard others say that the total weight difference is 125 lbs.

You can get a rachet/socket on all the nuts of an 8", but the bottom two of a 9" require a box or open end IIRC.
Rule of thumb I've heard here and from engine builders, an 8" will handle up to about 400H.P. and Ft. Lbs. More than that get a 9".

Well after lots of searching, want adds, bartering, "horse trading" I finally have a T5 to put in my car. I'm into it for $150 CAD ($110 USD) From all the research I did this will work fine for my "stockish" Sunday driver car. 1968 mustang 289, 3 speed.

Over the July 4th weekend I finally upgraded from a 3.00 to 3.55 gear ratio and I love it. With my 90-93 T5, I'm cruising at 70 MPH (approx. 2200-2300 RPM). I'm a weekend cruiser and I've put about 200 miles total on the build (15-25 miles short easy trips at a time)
Since I like to take...
