Replace front axle 4x4 drive actuator

[isd503]

I have the 1st generation actuator and it is not available anymore - Front Drive Axle Actuator - 26013495 (1st design, deprecated, w/axle codes ZLZ, ZGT, ZHY, ZKS, ZKY).
I think this is the 2nd generation actuator which is currently available: Front Drive Axle Actuator - 26060073 (2nd design, stamped ZKS, ZLW, ZXS, ZLY, ZXN, UM1, ZD2, ZWA, ZWB).
I think this is the matching harness for the 2nd generation actuator: Front Drive Axle Actuator Harness - 88959465 (replaces 12376316, stamped ZLS, ZLT, ZLW ZLX, ZLY). This is the harness I believe I currently have: 12376316 - (88-96I K1,2) AXLE CODE; ZLS, ZLT, ZLW ZLX, ZLY.
I found some markings on the parts below and they are in the attached pics:
Front Wheel Drive Shaft (x2) - 26062613
Front Differential Housing - 15572992
Front Differential Carrier - 26033234-4

Almost all of this information came from Internet sources. Is there anyone here who can verify this sounds right before I start buying parts? Left to right:

1 - Front Differential Housing
2 - Front Differential Housing
3 - Front Wheel Drive Shaft
4 - Front Differential Carrier

Also, is there any way to determine the ratio using this information?

Should always post your trucks information, otherwise we are guessing here.

Yeah all that, when just a simple “1988 K1500, need actuator” would’ve worked. It just makes it easier to get help. Seems like they are readily available though.

Can you post a picture of your rpo codes in glove box?

"Signatures" don't show up on mobile devices.

I second what @Caman96 stated. Help us help you...

This is the worm gear adaptor I bought for my '88 to eliminate the worn out TLA

They do, but the user has to turn the phone horizontally.

My mind is blown. I never knew it would go to the full page view, I always assumed it stayed on the mobile version.
------------------
As far as actuators go, I tried to install the updated electronic one but due to it being faulty I never got it to work properly. Ultimately wound up going with a Posi-Lok cable kit, I like it quite a bit, but the install was a little bit of a pain; having 2Lo is very nice when it comes to trying to push trailers around.

I have used the Posi-lok kit on a couple of trucks, after getting stuck in two feet of snow at Lake Tahoe twice, because the actuator wouldn’t work. The posi-lok has never failed me.
