I need to make a box for a 03 Ram 1500 reg. cab pickup, anyone know of any specs or measurements to make a box for this?

 

i made a box for my 04 ram and its pretty tricky. the passenger seat belt hump it a pain ill get pics and measerments up soon

 

not sure if the 03 has the "tray" behind the seat but my box fits in the tray..... i know its 8" wide at the bottom and 4" at the top if that helps... not sure how long but it holds two 10's... not sure what you want to put in and how many so...if you just put in one small 10 it should be pretty easy because it can fit right behind the driver seat without worry for the "hump"

 

I found a box on ebay but dont know if it will fit. Then I took the tray out from behind the seats and did some measuring, drew it up on microsoft paint with all specs, but it wont let me upload it to this post. It says bmp is not supported any 1 knows what to do w/ that. Off of topic, but does any 1 know how upload pics to a profile when it says pic file is to large?
