I have been told that an S-10 steering box will bolt on an early Chevelle, has anyone done this and if so does the Chevelle pitman arm have the same spline or is there a trick here? I have a '65 convertible and it is about 6 1/2 turns from lock to lock. Is an S-10 any quicker ratio? Thanks for any light that you may shed on this subject. Victor

I've heard the same thing...don't know though. What I do know is that the box from a '70's or early '80's Camaro/Firebird is a bolt-on, the Z-28/T-A boxes are 3 turns lock to lock, and a box from a Monza/Monza clone will also work. The pitman arms all interchange (same splines). If the S-10 box is a Saginaw that looks the same, chances are it will also work.
I have a '76? T/A box on my '65, bolted right on, works great. One final note, beware of incompatible internal steering stops. They can be made to fit I hear, I've never run into this problem, only heard of it. Hope this helps, Bryan

I don't think you want it. If you are now turning 6.5 turns I don't believe you will be any better off with the S10 box. I have a'93 S10 Blazer 4dr and get tired of cranking on the steering wheel to get this thing to turn. I thought I would look into putting a late model Camaro or TransAm box in my S10.

Hi
Dude what you want is an IROC steering Box. I put a 90 box in my 67 Chevelle bolts right up. You use your pitman arm all you need is a new rag Joint from Lee Manufacturing in CA and a new pressure hose. They sell the whole kit. I put a PST poly front end kit and for about another 100 bucks I turn Lock to lock in 3 1/4 turns feels like a dream.
Good Luck
