Hey Cab, Yes, I was referring to the early 300/MW rockers.
I just got a set with a 413 and was curious as to how disappointed I would be if I tried to use them with performance in mind. Wasn't sure if they were similar to the Crane or Isky adjustables overall and/or better than the stamp steel rockers for that matter. I'll measure them out at some point in comparison to the Cranes I have laying around, but given work and the holidays I was hopeful that maybe someone, I.E.(You)
had good info on them already to tie me over until I got time to look into them myself. -Trent
