Which year Chevy steering box is the strongest? (for crossover)

[Drew Persson]

Thinking about using a Chevy box instead of Toyota, with '76 Suburban tie rod ends.

It's not which year, but which one. You want a two wheel drive box....... damn near any year.

I am in this process too are the 1 ton boxes any different from the 1/2 ton or s10 versions???

Mid 70's GM fullsize cars have the 4 bolt box. There is a 76 cast into the box. Usually the best box to use. I'm sure there are other applications with that box.

Mine has the number 7802644 stamped on the side. The it also has a number that is 237 on it. Good one?? bad one?

Yep, you want a 2x4 box, one thing to keep in mind though, the input and output hoses changed from standard to metric some time around the early eighties, can't remember which year off-hand.

Yeah, like Steve said. 2WD box. from 65' to 79' GM used Flare fittings. From 80 and up, they used O'ring fittings. You need a box that uses the same style fitting as your pump. I hear that Flare fittings are better b/c no O'rings to go bad....

Thanks guys!

If you do get the differnt box then what you have napa can switch the end coming from the pump. I converted my fitting for $10 or so from o ring to flare.

the steering input shaft also changed diameter and spline count between 76-77
