Default 97 vs 98 4wd solenoid difference

I have a 97 and a 98 silverado. Both are 4wd. Im in the middle of swapping engines but I noticed my 97's solenoid for the 4wd looks tiny and almost nothing compared to my 98's. The 4wd engages very slowly and near silent on the 97 but you can hear a clunk and its quick in my 98 which I like.

Can I swap these solenoids?

Has no one ever seen such a small solenoid on a 97 silverado before?? I am wondering if it came from a different truck and if that's why its not working correctly.

Is the top one an older thermal design? I read in a post on at the link below that this might be an older design and I could just convert over to the newer design that I like.

UPDATED. Ok yes that is an older thermal design. GM had issues with them and replaced them with the electronic design. You can convert it over you just need to either splice in a wire.....somewhere to the sensor above it (no 100% sure which wire yet) or buy the conversion harness at the link below...

The main problem with these older designs seem to be the problem I'm having....VERY SLOW ENGAGEMENT. Gets much worse as the outside temp drops since there is a fluid which gets heated up to allow it to expand and push what ever rod or actuator arm out to engage 4wd
