This is my modified box. Saginaw 605 with an extended housing and a modified Fairlane sector shaft. Works great.

 

Do you have details or plans of the modifications you made to the Saginaw box. I really like the idea of using that steering box. Did you modify the steering column or change to another?
Thanks,

I got my info on the mods from this site and went from there
605 Power Steering conversion for the tri-five Chevy's

I had to use a shorter steering column since the rag joint is right at the firewall/floor area. I had an old one from a 68 Cougar lying around and shortened that. It is collapsable too so I have a little extra safety built in, in case of a collision I lessen the chance of being speared! I used an early Chevy pump with outlets from a later pump and the high pressure hose is for an 1986 Cavalier. I had to slightly tweak it.

 

Thx for the pics... I believe this is a Cadillac Catera box, 1999 vintage or so... These are rare in junkyards around me, but I like them because they are integral, plus they are aluminum....

 

Caddilac Catera & Opel Omega same car technically...
Here in europe it is just Opel

Caddillac BLS is actually a Saab

Isn't this a Camaro steering Box? Above info says 77-81 Camaro?

Stvrr-- I like the Saginaw 605 box because it looks to be very close to the same size and location as the original Fairlane box. I have a 390 GT four speed and the clutch rod runs very close to the steering box. Is yours an automatic or manual transmission. Do you have any pictures of the 605 box mounted? I may have to try making one of these. I think it will work for me. Any more details would help a lot. Thanks a lot!!!

My car is a console shifted auto, so I didn't have to worry about any other things in the way of the box.I don't have too many pictures of it when I was doing it. When I modified the sector gear, I compared the profile of the original sector and the sector from the saginaw box to see where it needed to be clearanced with an optical comparator(shadow graph). I work in a machine shop so it was no problem. I had to cut off the outer two teeth and had to deepen them a bit also. I blued everything up and assembled it to see the pattern,much the same as you would do a rear end.

 

I have access to all the equipment needed to do this, and a few tool and die maker friends that will help if I can give them the proper information to work with. Did you use the Fairlane shaft in the Saginaw box? Were the teeth the only thing you had to machine? I'm sorry about all the questions, just trying to get it all straight in my mind. I'll probably have more. The additional pictures helped me, also.
Thanks,

The bolt pattern of a mustang box where it bolts to the framerail is different than the Fairlane box. I have a self modified 605 box, which is better than the stock leaky power steering, but it far from excellent. I will need to have a look at these catera boxes!.

 

Interesting. A friend hauled the box out of his '66 Falcon up here, we laid it on the floor next to the Borgeson box that was going into my '65 Mustang convertible, and the output shaft lengths and mounting bolt pattern were identical.

So at least insofar as '66-early '67 Falcons and Fairlanes go I'd tend to think they should be compatible. Other years I can't make any claims about.

The Falcon box of course had the spearing column integral to the box, and pretty much any conversion is going to require modifying that.

If you're looking for something bolt-in you might give the guy at ABS Power Brake a call, I think he might do a custom bolt pattern on their setup.

 

Some good info. Thanks.

 

Maybe the 65-66 Mustang boxes have the same bolt pattern. The 67-68 are different. I grabbed one from my Dad's parts car Cougar(same) and it didn't work.
