Rockers and pushrods

Well I finally managed to break one of my stock stamped rockers. I have a set of iron ones but want to put adjusters with lock nuts on instead of the interference fit adjusters. Anyone know the thread 3/8-24? Haven't went digging to find them just yet.

Also does anyone have a measurement for length of pushrod. I see several different length ones listed on summit but there is 1/8" difference between them all.

I know I should really measure, just being a little lazy.
