scupper thru hull replacement

[johna]

I know some of you guys must have done this, on my 1985 18' SF I want to replace the thru hulls and 1 1/8" hoses for the deck drains. The hoses are cracked, probably original and the fittings are nylon so if I touch them they might crack and so it's just time for new. I think I found a nylon replacement but was wondering if there is chrome or bronze that would work. Most bronze I saw had flanges too wide to fit the scupper flappers back on.
Problem has been finding thru hulls that are a straight 1 1/8" as the hole in the transom is that size. Most I found change diameter before or after the transom. The deck drain
fitting is also 1 1/8" so it all has to be that size.
Any suggestions or sources?
