340 adjustable LOCKING rocker arm kit

Well that ain't good. Crane doesn't make the whole kit anymore. I got the last Crane small block adjuster kit Summit had a year or so ago for my slant 6 build. They've not had any since. I called them and sure enough, Crane's not making them, because Crane's not makin anything anymore since they are no more. S&S Cycles bought them out and I guess it didn't work out, so Crane is officially gone.
i can't help but think any good quality nut will work ;)
