I actually prefer the OEM spring clamps. Toyota knew what they were doing and found the spring clamps to be plenty reliable. Considering that the OEM clamps worked on my truck for about 25 years before I replaced the original hoses (still looked just fine, but 25 years is quite a long time), I felt that the cost to longevity ratio here was pretty darn good and bought new Genuine Toyota clamps with the Genuine Toyota hoses. Sure, they are more expensive then the parts store special, but how often do you actually expect to replace the hoses and clamps?

same here. replaced all the clamps and hoses with genuine toyota after a 32-year run on the originals.
I have not seen what the OEM hose clamps on the radiator inlet and outlet hoses look like. Are they the spring steel ring type without any screw mechanism (unlike those on intake duct)?
Like this?
Do OEM Radiator Hose Clamps Look Like This?
BTW, one detail I forgot... THE TRUCK SHOP IN SAN DIEGO (MIRAMAR) DID A SLOPPY JOB ON MY RADIATOR REPLACEMENT. See pic below, and details here. I found a dent on the port on radiator where inlet hose connects to. I have fixed pressure worm-drive clamp there now that I had to adjust when I saw a leak. I'm concerned that the spring type OEM may not have adjustability to adapt to that dent. I may replace that with the screw-drive Tridon with Belleville spring^^^.

I'm pretty sure that part is brass, so it should be easy to bend. Hack saw an arc out of piece of iron pipe of the appropriate size, and using vice-grips just push out the dent.

not exactly. the upper hose uses the spring at both the radiator neck and t-stat housing, as in these pictures:
the lower hose does not use spring clamps, rather, it uses clamps similar to those used on the intake tube.
NORMA TORRO non-perforated worm drive hose clamps are pretty dang good too...top quality. Will not damage hoses like standard worm drive clamps. Band has rolled edges.
Bought a box of 10 from Amazon for $10.42 shipped. These are W4 rated which means all of it is made from 304 stainless.
Box has a sticker on it that says made in USA. On the inside of the band, they are stamped made in Germany.
