Outriggers sizes are either 1-1/2 or 1 1/8. The elbows/bases are 1 1/4 outside diameter. The ones I have are 1 1/8 so they will fit your application. Here's pic.
I looked really quick for the elbows and I don't think I have them any longer so you might have to check out Ebay for them.
I live in Fredericksburg, VA - so not to far for shipping and they don't weigh much if your in NC.
