Looks nice. Firmer than OEM, so you feel the engine more Rated by Willy on December 01, 2021
Summary: Most of the OEM listings were for the 'clamshell' style where the big part is bolted to the frame, with just tabs on the engine. Most engine swaps use this style, where the frame just has a through-bolt mount.
