This mount works perfectly with my chromoly crossmember. You can also use this mount to fabricate your own crossmember for your specific chassis swap.
From the factory Prothane includes the bolts for the crossmember, but not the two M10x1.5 bolts for the transmission. To make you a happy customer, I include these with every mount i sell.
Factory rubber transmission mounts were never intended to take much abuse, so the resultant sloppiness in your drivetrain can be largely traced to them. These mounts are designed to control torque and eliminate breakage. Where applicable, they feature the polylocked “run-safe” interlocking device, so they won’t leave you stranded like you a broken stock mount will.
