Installing steering gear box - The 1947 - Present Chevrolet & GMC Truck Message Board Network

ebaby35 · 06-16-2017, 09:51 AM

Ok I picked up from a junkyard a 1990 c1500 gear box for my 1964 chassis with a 85 suburban front-end. On the c1500 it was located on the inside of the chassis but on my chassis it's too big to go on the inside due to the c channel. Is there any modifications that I need to do or am I mounting wrong. I was under the impression that a 1990 would work.

I always thought the cutoff year was 87' for the steering box unless you get it from a Suburban or a OBS Crew cab then it would be up to 91'.

damn your probably right

chevy_mike · 06-16-2017, 11:25 AM

Yep, up to '87 from a truck, '91 for Suburban

Ok found another one it's a 91 suburban but it's a 3/4 does that matter

Hopefully someone will chime in but I "think" they are the same as far as the box and pitman arm goes. I am fairly sure the tie rods are different but you're not using those. You might search on RockAuto and compare the 1/2 ton and 3/4 ton part numbers for a steering box. That would help confirm the box. I am not as well versed on the total difference between the 1/2 and 3/4 ton items.

Ok I got a 91' suburban gear box today and tried to bolt up to 64' chassis. Is there a adapter plate so it rests flat ag ain't the frame? And can I use the same holes?

Yes there is: http://www.67-72chevytrucks.com/vboa...d.php?t=332923

Yep, Captianfab's adapter is the only one I use. I have done two trucks with them. It will require drilling a few holes. It comes with a template which makes it really easy.

My congrats to ChevyMike for an excellent "run" of pics on installing & using that adapter from beginning to finished project. Thanks from many who hopefully will look at your post when they install ps..
