Need some window weights or large rebar

[Rainmaker]

Anyone have any idea where I could get some old window weights or some Rebar? It looks like #11 rebar is about the right weight to length. I am looking to make some inexpensive deep drop sinkers.I need a bunch of 4#, 5#, and a couple of slightly heaver ones. I dont mind paying but I can not find anyone who has the larger rebar in the Stuart area. Any ideas?

(the window weights are a reach but they work well....)
