Flat Towing 1974 Blazer

[Cadillac Kid]

Hello everyone. I have a question here. I'm looking at picking up a 73-75 k5 Blazer.


I wanted to see if it is possible to flat tow a k5 that has a NP203 full-time 4x4?
If it can not be towed 4 wheels down, would a part time conversion and swapping to manual hubs on the front make this possible? Have to convert to a np205 possibly? I searched the internet and could not come up with a solid answer, weather it is OK to tow a full time np203 4 wheels down.
I love the squarebody's, but I'm limited to 73'-75' because of California.
Yeah, I know…

Thanks, in advance.
