THERE IS THE QUESTION, "ARE 400EX and 450R A-ARMS THE SAME???" Thanks

 

I've been searching for the past 30 mins and I found the answer. From what I saw I believe it is NO, they aren't the same. If anyone knows different tell me. The one thing I have searched for and havn't been able to find is a measurement on a 400ex. I am lookin for the distance from the upper right shock mount to the upper left shock mount, if anyone can measure this for me I will be very HAPPY. Thanks
