Thinking about putting the Corbin style radiator clamps on my car. I know the alligator style are the better way to go. Looking for Pros and Cons. Thanks in advance. Rob 
If you can't be smart.....don't be stupid!

When I bought my new 69 RR, the first thing I did was clean off all those silly grease pencel marks. The second was put on proper radiator clamps in place of the flimsy factory jobs.

I always use the factory clamps but have noticed they are different. I can't put my finger on it but I think the guage is a hair thinner. I have had leak problems in the last 2 years I have never had before. I had a lower hose blow right off the rad outlet with an NOS hose. Another problem is the hoses (all the hoses) are a thinner wall - The I.D. is right but the thinner wall thickness makes for a smaller O.D. which does not give the clamp enough meat to bite around. I put an original clamp on that lower hose and all is good. I think we have to start using clamps 1 size smaller than normal to compensate for the reduction in hose O.D. and for the (seemingly) reduced tension/guage - whatever the problem is with these new clamps. I had the heater hoses and the by-pass hose (smallblock) leak with these newer hoses/clamps. And- if I don't have NOS I use the best hoses I can get with the same issues.
 That's what I noticed too. Don't through any original clamps away just replate or paint them. I've (sometimes)found that a leaking clamp can be stopped by shifting the clamp on the hose.

I been using the repro clamp kits, original corbin clamps, NOS, or reconditioned,......newer hoses, even repro hoses are thinner, hence the clamps won't seal properly,....squeezeing the clamp to be "tighter" dosen't work, it only causes the clamp to "egg" in shape, and thus squeezes on the sides only, causing a leak,....I've found that purchaseing the clamps directly thru the manufacturers, I can purchase them in 1/16-1/8 inch increments to the sizes I really need for a tight fit,.....

Mike, where do you order the custom size clamps directly from? What is the correct diameter? I like the spring clamps because they always give constant tension, where the screw type ones they get tightened to a certain point only.

. All worked well except the upper radiator kept leaking. I ended up using a worm type there..
