In 2003 I had to take my MP base and a dropped base from another assembly to a guy who melded the two together. He tig welded them and it looks great. I dont know if anyone has stepped up to fill this void, but it would certainly help people. My 70 Charger with a 440/493 and Performer RPM intake needed more clearance to the hood. The TIG modified base gave me 1 1/4" more drop. That was just right.
