I have found the new silicone coolant hoses come in a vast offering of sizes, bends and reducers.
I bought some from the UK on eBay just recently for a little project on 2511. The link below is to the seller. They have a WAAAYY better selection than any USA vendors I could come across. My last order from them took 5 days to arrive - yup, UK to California in FIVE days.
To convert their metric sizes:
35mm = 1 3/8"
38mm = 1 1/2"
45mm = 1 3/4"
They offer them in black, red and blue. I picked the black.

They have straight and 90/45 degree elbow reducers, too.
I found the best pricing on good SS T-bolt clamps from Summit.
I have successfully used these from them:
for the 1 3/8" hose...sme-240175
for the 1 1/2" hose...sme-240200
