have been using the search option for about 3 hours but i
can't find much related info. certainly after reading that the
casting numbers (7826692) are useless...

i want to swap my manual 24:1 (feel like a hamster sometimes) steering
box to a nice power steering one.

have been looking at one from a cadillac, but wasn't going to work.

now i found one from a 79 Pontiac trans am. so called WS6 ??
should be 2.5 turns lock to lock.

i presume i can use this one hence the right parts ?

biggest question is: if i order a (69?) PS pitman arm, will it fit right on
the output shaft. i have read several times that the output shaft
of a manual box is smaller. this was also so on the cadillac one.

so it should be fine with the right:
- pitman arm
- rag joint
- power steering hoses.
?

There are a number of posts on converting to a 3rd gen iroc box and here is one: http://www.camaros.net/forums/showthread.php?t=29658
You will need to use hoses with the correct ends for the newer box or fittings to connect older style ends to it. You will also need to get a p/s pump and brackets of course. Good luck.

The Iroc and WS6 are one in the same. Read the 3rd gen steering box sticky. Its very good.

P.S. No one believes me, but if you use a pre 1980 Iroc/ws6 box (79 is what I used) the fittings are standard not metric so no adapters are needed

hey thanks larry.
haven't found that topic. all good info.
only thing is, if it's a 79 box, doesn't this mean it's a 2nd gen instead of
a 3rd gen ?
if i have read somewhere correctly i should need original hoses ?

ps pump and brackets are allready taken care of ;)

ok, thanks.
i believe you ;)
technically speaking a 79 box is a 2nd gen instead of a 3rd gen.

i have allready read the sticky a couple of times,
the link to pozziracing: http://www.pozziracing.com/camaro_steering.htm

400bird,
The hose fittings changed to M16X1.5 and M18x1.5 metric o-rings starting 1980 model year. So any gear before 1980 will have 45 degree flare seats and 5/8-18 or 11/16-18 female ports.

However, the power gear input shaft was changed to 3/4 dia starting in 1977. So you probably will require a new flexible coupling to fit the 3/4 gear shaft.

Yup, I did get a new rag joint.
At the time I had no idea when the model generation changed. Wonder if the box I have is different than a regular 3rd gen box? Its still 1000x better than stock.

A 79 Z/28 or TA used a 14 to 1 box, unlike older Z/28's and TA's the box in 79 was not variable ratio. It did have a fairly stiff feel. The IROC/TA box is 12.7 to 1. A 3rd gen F body with the "good" box, will have 16" wheels.

Hey Guys,

i am trying to figure out what hoses i need to order.
the box is from a 76 car.
so original PS hoses should fit, but ...

on pozziracing it stated:
--
Power steering pumps use three types of output fittings, the 60's standard 45 deg flare with male end on the pump, the 70's inverted flare with female end on the pump, and the 1980 and later metric Saginaw fitting with O ring and female end on the pump and box. Most older pumps must have flow and pressure boosted to properly operate a fast ratio box.
--

i have a PS pump from a 85 big block...
so the pump-side of the hose will not fit, right ?
the return side is of the barb-type, so that shouldn't be a problem.
but what about the pressure side ?
