So I've been looking to get a new steering box to replace my original one in my '72. This is because I'm really unhappy with the slop and loose feel that my current box has. After a little research I've decided to go with a Lee steering box but would like a little input on which box to choose, either the 800 or 670 series? The car that this box will be put in will be used for street purposes only in the hopes that it will provide a tighter feel for the road at freeway speeds as well as on whinny roads. I've already done some work to the suspension including completely rebuilding the front end, new shocks and springs and even adding power discs, which have only seemed to magnify the poor effects of the steering box. So would the 800 series be sufficient for my needs or will I later wish that I went with the 670 series? Any input about both or either box will be appreciated thanks!:D

I think you might like the 800. But before you purchase it you might think about the local wrecking yards.
The preferred high-effort, quick-ratio steering box was offered in the following cars: the ’83-’88 Monte Carlo SS with HD suspension, the ’83-’88 Hurst Olds/Cutlass with HD suspensions, the ’84-’88 Buick Grand National/Regal with FE2 and FE3 suspensions, and the ’86-’88 Pontiac Grand Prix with touring suspension.

Working with your local wrecking yards, you can use the Hollander interchange number 1282 to identify this given steering gearbox. Or, as you’re scrounging around in search of this trick steering box, look for the “YA” stamp that is located on the end cap of the steering box. This stamp is very delicate and is easy to wash off, but it’s the only way to identify the box at a glance.
The only other thing you would need is the rag joint that Lee sell to mate them together. Hope this helps.

Thanks for the tips, I'll look into that and see how things go. I'm just not that experienced when it comes to swaping out parts from one make of car into another and the fabrication that is sometimes necessary to do those kinds of things, which is why I was interested in Lee's 800 or 670 box that I know work in a Chevelle.

All junk, internal stops will make u-turns a 3 point affair. Look at SC&C for a nice 670 series box.

Now Dennis, they are not ALL junk ;) But the chances of finding one with the critical letter codes still on it and visible are very slim indeed.

There actually are some swaps that are close to bolt-on. And there is a lot of info here if you do a search on these swaps and exactly what is required. Jiml82 posts info frequently and has the definitive paper on the subject. Search for "steering papers".

All that aside, one of the nice things about Lee's boxes is that you know exactly what you will get. From what I have read Tom Lee will discuss and help you figure out what you need if you give him a call. From what you have said, I would bet that an 800 box with a larger T-bar will make you very happy.

I recently did a swap into my '68 with a box from a '92 Camaro that actually DID have the letter codes still legible in two places. Yes it did have different steering stops than a Chevelle box. Operative word being "did" ;) I also had to pick up the rag joint coupler from a pickup and just converted over to all metric O-ring hose fittings (rather than do the adapters that Tom Lee sells). But then I have learned my way around the inside of a Saginaw steering box too. And I am VERY happy with this box :beers:
