I am having difficulties finding a correct replacement ps gearbox. I did research on the forum and I know other members have had the same issue. I am having a particular issue, I ordered a box with a similar/same looking bolt mounting pattern. As it turns out the snout going to the steering wheel shaft is 1 and 3/4 inches longer on the new box. I do not see any way this new box could work on my truck. Am I correct about being unable to use this box? I am wondering why the seller would list this box to fit on 1981 to 1988 2wd truck. Is it possible this box is for a 1 ton truck. Did the seller error in his listing?

Reason: Grammer
I have a power steering gear box available from a 2WD 1986 Toyota Xtra Cab pickup. I'm in the Tucson AZ area and can send you pics and measurements if you're interested.
The story on the truck was one of the kids ran it out of oil and siezed the engine. Dad got pissed and cut the truck in half and took the rear for a trailer. I only wanted the cab but I had to buy all that was left. I sold the front clip, the engine as a core, scrapped the front section of the frame and I have the A 43-D auto trans and power steering box left. I won't throw out stuff other guys may need. I don't price gouge people either.
I am expecting/hoping to receive a remanufactured unit soon (GM 19321468). I still could have an issue with the input shaft being too small. One other possible solution is having my old unit rebuilt through O'Reilly. But that would likely be very time consuming. My truck is been out of commission since December, I would like to get back to using it. Thanks for the offer, I going to see how things turn out with the GM remanufactured unit in the next couple of weeks. Those are good parts to hang on to. Mine has the automatic transmission and I have a 150K miles on my truck. I have considered the possibility of having a spare used automatic transmission. I have no interest in driving a stick in big city traffic. Been there, Done that.
If the photos are accurate, it appears to be an original Toyota unit that has been remanufactured by GM (or by someone that meets GM's standards?) Now if the input shaft is the correct diameter is another question. I wonder if there is coupler available from the Dealer that matches up with the smaller diameter shafts? The issue with the steering happened suddenly, Turning the wheel right (cw) there was no problem. Turning the wheel to the left (ccw), there was a dead zone for over 1/8 of a turn, The problem seems to be isolated to the box. Manually moving the wheels, with the front end off the ground, did not indicate any issues with the linkage. Steering was tight before the issue started.

Yeah removing the pitman arm was a bit of an adventure. I bought a removal tool from Harbor Freight. Initially, I didn't have any success using the tool. So, I sprayed the shaft with Kroil and let it sit for about a week. Then, I gave it another try. I used a 3/4 inch drive impact socket and a pull bar. I tighten it as much as I could. Then, I set it down. About a minute later, there was a pop and the pitman arm went flying.
This feels like I going down the steering box rabbit hole. I am wondering if I could use the new box with a different (shorter) steering shaft I found some information, on the other forum, indicating the next generation is using a longer snout A photo with an example of two boxes with the same bolt pattern and different snout lengths is shown (It isn't my bolt pattern). Could I find a steering shaft from a next generation salvage truck/4runner that would bolt up and be shorter in length? I tried to post a link to the relevant thread I could not. A link is embedded in a thread on this forum. In general the boxes with longer snouts could be superior in durability, In other words Toyota may have upgraded the steering boxes on the next generation. Since I am not the only member who has run in to difficulties finding a new replacement box that fits, some out of the box thinking may be worth considering.
One inch difference in snout length?
A part number is being used by different vendors for two versions of the gear box. Cardone has an oem remanufactured unit listed as 27-8470. This unit appears identical to my old box as does the GM reman unit. The new casting with the longer snout is also listed with the same part number. I measured the travel on my steering shaft and it is 1 and 1/4 inches. As is it stands, the longer snout appears to be a no go on my truck However, I can not rule out the possibility that other 1986 Toyota rwd pickups have shafts with more travel that could accommodate a 1 and 3/4 inch longer shaft
