how can i tell if my 83 T/A is WS6 being the RPO sheet is gone? it has 4 wheel disk, i assume a posi (limited slip) from the way it acted when i did burnouts, the sways look fairly close to my 89 formula in size and it is a 5 speed hardtop car.
something else i noticed about my 83 is it has pwr windows and antenna but manual mirrors ,tilt no cruse , hatch pop ,and teh motor is LG4. i got that from the VIN. i plan to give PHS a try and see what comes up.

 

The PHS documents will tell you for sure.
Great stuff to have with your car!
Usually, disk brakes are a giveaway, but throughout the years, people could change swaybars and rear ends.
PHS is the way to go!

Let's see some pictures!

 

this car was all orig when i got it so there wasnt a rear change and by looking at it when i got it it was obvious.
as for a pic, its appearance is quite sadd but in general its actually pretty solid. i'd rather post a pic when i get it cleaned up some.
heres a pic of my 89 formula this past may at the national F body mailing list event.

also something else about my 83, its med sand grey/black lower half. cream grey black on the int. i have only seen 2 others in my area and one other fella on the site has one. other than those i havent seen any other 83 T/As in this color.

 

1984 was the first year for the SPID RPO label so you wouldn't find one on the car anyway.

Its possible the build sheet may still be in the interior of the car. Check under the front and rear seats in the springs. It could also be under the carpet or behind the door panels.

Other than that, getting the dealer invoice from PHS is the only way to find out. I don't think dealers can pull up info on a car that old. I think their computers go to around 1990.
