Overall length of Powerhouse and SS valves? Disco tube

[mackeral5]

I am about to install a Prod gauge port in a gun based on a disco/prod diameter tube.  Some day I may opt to install either a Cothran Powerhouse or a JSRA SS valve and I want to make sure I leave enough room.  Can anyone please share with me the OAL of each of these valves?  This will help me determine where to drill the gauge port hole. 

Thank you in advance!

It should be the same as a disco oem valve. The Prod, Disco and Maximus use the same SS valve.

Thank you for the quick response.  I don't have an OEM disco valve available to measure......

I found an old post by rterne that showed 3 different disco regulators, the top on was a Cothran Powerhouse.  The Powerhouse appeared to be a bit shorter, so if someone could please measure an OEM disco valve's length that will help.

Anyone have a disco valve and a measuring device handy?  I am looking for overall length of the valve , not including the poppet stem. 

Thank you.
