It's Down until I get the propshaft off and into the driveshaft specialist's shop. It caught a big ding when I got broadsided in 4/22. The shaft was pushed hard into the side of the hole in the Trailing Arm Crossmember. The dent went unnoticed after fresh Trailing Arms and a rebuilt 12-Bolt differential were assembled to the chassis. When I got excessive vibrations above 59 MPH, we put it on a rack and found out. I have not dropped the propshaft yet. Waiting to line up mechanically-inclined friends to operate.
The truck also steers two points to the left -- so the Frame may be out of alignment. An alignment shop said they couldn't deal with my problem.
So much for my sad story. It can still be fixed.

I see an elongated booster in front of your master brake cylinder. Is that Hydroboost?
And is the P/S Pump bracket a 292-only one, or could you modify a 250 unit?

I don't see a need for Power/Steering on my Stepside. It's usually underloaded and I don't have problems handling it, but I'm pondering building another 292 for my '67 K/10 Suburban. That was a beast to pull around. An attempt at adding P/S failed due to an earlier style of steering geometry. But a Dana 44 front differential w/ P/S and P/Disc Brakes from a '71 MY or later would fix that.
Sorry we are sailing far afield of the OP's querry RE Fan Clutches, but the '67 Sub had a 454, also with an unclutched Flex Fan.
I remember the ordeal with your stepwise, but thought you had that all taken care of, maybe a different frame would be your best bet. After I switched it over to disk brakes I need a new proportioning valve and also need a different booster because of the 4 barrel carb. I bought the whole package including master cylinder. It's not a hydroboost that I'm aware of.
The PS is original 69-72 I believe, as you know like hen's teeth to find, worst than the frame mount. In searching for this one I bought parts of one, I have an original bracket that the ears are broke off from, the bracket it self is fine. A person should have a block that it could mount it to to check alignment while welding ears back on. Was going to do this till I found the one on my truck. Not in any hurry to sell it but if you're interested we could talk.
