I've got an 88 formerly automatic N/A, and the previous owner had removed the power steering. I've done my research, it's a 3-port rack, blah blah blah...

The snag here is that the mounting hardware for the P/S, A/C, Idler bracket is gone. As hard as I try, I cannot find out exactly what studs and bolts I will need.

 

The bracket use both M10 and M12 bolts. Very common.
Rx7s came with 2 and 3 port so find a correct power steering pump and hoses. Bracket is the same for all.
All the pulleys are the same .
If the rack ports were left open, I'd bleed it out .
I have no idea why people do a such a thing. If you do a half *** job at it, steering feel sucks ***.

 

What's the thread pitch? Length? Could have sworn there was at least one stud involved (from memory).

As I said, I did my research.... 3-port racks are S4 and S5 TII, while the 2-port racks are S5 N/A.

Additionally, 3-port racks are velocity (speed) sensitive variable assist systems, while the 2-port S5 systems are RPM sensitive.

 

You should have some bolts laying around don't you?
You can figure the pitch and lengh.

 

Unhelpful response from someone who just doesn't know.

 

Goto the junkyard if theres one that has an rx7 and get them if they're in a place easy to access.

If I had a reason to go back to the junkyard that has the s4 se model 6 miles away I'd get them for you.

 

I live in Vermont, where these cars very rarely show up in the few yards we have. That option is out. Aron, if you could do that, it'd be awesome. OEM FTW

 

I just pulled a manual rack from a SE to swap into my TII I can let send you pics if you need.
