Firewall Wiring Bracket - Which One?

[Orange Bird]

I am finishing up some of the details on my 70 RR restoration and have a question about which firewall wiring bracket I need - long or short version. I have a power brake car and the bracket is the one that mounts to the booster plate. It fits behind the plate and kinda folds over to the front. The way I read the write ups from various restoration companies it seems that either one could be used. Does it matter? or does it matter depending on certain option packages, ect? does one route the wires better than the other?

I'll update my photos sometime later as I started a thread some time ago and it has been burried in the Body Paint Trim section. I'll move it forward soon.
Thanks

 think its short for power brakes  ,  there was a thread on here sometime ago , cant seem to find it at the minute   think Bill Alphin done some investigation on this  , as he started selling both versions , with the correct plating etc

Thank You for the information. I saw a few pictures of various vehicles and it seemed to show both. I appreciate the response.
