I bought my driver's side mount from Chrysler Power magazine. It is a solid mount. I drilled the mounting bosses on the passenger side of the block and used a stock 440 mount on that side. The Aruzza driver's side mount is almost identical to mine. The passenger side mount he sells is better because it bolts to the block where the hemi mounts bolt. I tried the Schumacher mounts on my car and they raised the engine and caused some hood clearance problems for me. I am running a 3" oval air cleaner element though.
