posi-trac id ?
I have a 69 T-Top and a 63 conv. I know the 63 is not posi-traction. I am trying to find out how I can determine if the 69 is posi or not. Anybody out there know an easy way to tell ?
Thanks

Jack up both sides. (both rear wheels off ground). spin one wheel by hand. If the other wheel turns the same direction you have a posi unit. If not, the opposite wheel will turn the opposite direction.

I have never seen a posi that turned the opposite direction. I've never seen a non-posi that turned the same direction so I think it works. How could it not work that way? 
BTW... In 69 positraction was still an potion but required with certain engine/trans options an gear ratios. I believe posi became standard in 1970.

My 69 has a big warning sticker on the underside of one of the storage compartment lids, I think the jack storage behind the pass seat. It says something about positraction equipped in big red letters.

Posi or not Posi...that is the question!
Have you checked the bottom of the differential carrier housing just in front of the rear end cover for the code?
Should be something like "AL-04 09 W". If your rear end is posi it will have an "E" below it.
