The closest to flat I found for mine was an FSJ. I got it from [USER=67]@Jody Treadway[/USER] a while back. I could go out and measure, but off the top of my head, it's around 5.5-6" hole C-C and 1" drop of less.
Another option is the PSC flat/undrilled arms. They're a tidy unit but a bear to drill without using a drill press, and heaven forbid having to ream one.
