GM 3.9L V6 Motor Mount Plates

Motor mount plates for the GM 3.9L 60* V6 such as the LZ9.

Universal traditional style motor mount plates to build your own motor mounts off of to your specific chassis. These are laser cut out of 3/16" HRPO. Enough flat space between the 4 M10 mounting holes per side to attach a 1.75" tube. I usually run these plates on the block with a 1.75" DOM tube standoff to a poly bushing welded to the end of the tube, then tabs mounted off the chassis to attach to. I use universal poly bushings from WFO with a 1/2" bolt, the advantage to these bushings is they also sell aluminum bushing inserts so you can use the same mount but have a solid mounted drivetrain or just use the aluminum bushing for mockup and welding to prevent melting your poly bushing.
