Radiator Hose size

I'm tired of loosing upper hoses to getting cut by my belt. What are the end sizes need? Gates PN 21589 lists 1 3/16" and 1 5/16 ends where as 25253 lists 1 1/4 for both. I'm getting on of these tomorrow when it comes in (maybe both) but which is right?

When I put the engine in I know its possible I may have bent the housing a bit and this is the problem, so I plan on trying to bend the tube toward the radiator a bit.


Any one have experience with stainless hoses? What length would be suggested?
 
Went with the 21589 again and trimmed it a bit more this time; clears belt easily. I went ahead and measured the t-stat housing and radiator with my calipers and both came to 1.3XX so I take that as 1 5/16, which means none of the hoses are right.
