Build it yourself.. One reason we did this video was due to the quality of the aftermarket rebuilt valves...
And.. I must say we had a bad one we rebuilt last month... When we got it back from the customer it appeared as if we cut the seal on the final assembly. So take your time, clean everything and save money... You can spend it on something else.

The rebuilt valves have been a crap shoot for years now. The new ones have been the way to go although some have told me they had some issue with those in the recent past as well.
For my 72 I rebuilt it about 12 years ago and I see it is weeping a little but it might be the hose connection. When I laid out the new hoses over the old originals I found the radius wasn't as large and the new hoses were slightly shorter over all. I got them installed and they worked but the point is to check them against what worked- if you still have them or are changing them out for the first time.
For my 69 I will be staying with the manual setup, really works nice and wasn't too bad in parking lot spaces, even with old 60 series tires and worn out bearings!

Thanks to all for the input. After cleaning the PS control and adjacent areas there's more fluid dripping from it. Haven't decided yet to rebuild or replace it.
Closer inspection of the engine compartment also shows what looks to be a leak from the steering box. The entire box is covered with a dirty greasy film, as is the frame rail beneath it all the way back to the drivers side door. Looks like I'll be taking that apart too for replacement of the seals at least.

I make a bolt for putting grease back in the gear box... and that may solve your gear box leak issue.

It is common for people to put oil in the gear boxes and/or the grease has had condensation form on top and leaking out. If you put oil in the box it will leak out the side every time.

If there's been condensation in there, I'll probably be in for bigger issues. Could be some corrosion I'd bet. Maybe a rebuild, not just seals.

Good to see you back.
Now if I can just get Lars back on a consistent basis as well.

I’ve recently been through this process! The PSCV on our ’78 has had the occasional drip every couple of weeks for about 10 years. The thought of changing/rebuilding was a bit daunting for such a tiny leak. But, after a 1600 mile trip to the south of France it got worse, so I bit the bullet.
I’d bought a repair kit from Corvette Central some years ago, so put that in, using the video on the Wilcox site along with a very detailed “how to” guide in pdf form. The job actually all went much better than I’d thought and so far, it’s nice and leak free, some 1000miles later.
I had cleaned everything down fully to ensure that it was the valve leaking, not a hose or the cylinder. It took a few days and some short runs in the car to be sure.
As an aside, I also changed the cylinder seals. I found no useful on-line info on that job! Thankfully, it was actually a doddle, with a lot less parts inside than indicated in any of the guides I read. The only difficult part was removing the “snap ring”, which had ludicrously small holes for the snap-ring pliers! I had to use a pick and was not amused!
