The steering boxes cover from mid 60's all the way to 87. What happened here is chevy changed the style of the fittings from inverted flare to o ring. This happened n the latter part of the 70's. Also...if u get a box with metric adpaters,this is 1 from 80's. With all that being said u have variable box from the mid to later 70 model yrs. It should have variable ratio. Last pic looks like the bronze o ring adapters n the box. U have to use them or it will leak. U joints are ALOT stronger. U have to get this done so if u can change out n the next few days then go 4 it. If it's gonna put u n a bind 2 get done, then just get it back together and worry about it when u got more time. Some where down the rd u might want 2 take a look at replacing the ball joints and tie rods. Wouldn't do that till warmer weather. When u get it all back together, raise front end with both wheels off the ground and move wheel all the way left and right. Leave cap off ps resivore. Move it a few time each way then add fluid as needed. Takes about 20 /30 times 2 get all the air out. When u stop seeing all the bubbles at the top u got the air out.
