well its a simple drawing u can just redo that on solidworks or autocad and save it as pdf , the part is in perspective so even if u want to edit it lets say as a image it wont give u a good result , i think the best way is to just draw it again .
Damn was hoping i had a chance not to draw it for i dont know the measurement for all the holes on the plate for i really need Them for my custom plate i Will draw to my mega build :-(
