  • Ford OEM transmission mount and weld in mount pad needed to modify the transmission cross member
  • Transmission tunnel cover with Hurst shifter boot to seal out exhaust and under car heat.
  • Shifter handle to work with stock Marauder or Crown Vic sport console with leather shift boot and Hurst shifter knob
  • All necessary hardware and wiring accessories included along with installation suggestions

This is not a bolt in kit!  This includes everything needed for installation but welding, cutting and modifying is necessary and not included in the kit.  Driveshaft will need to be shortened and is not included in the kit.  These kits are built to order and may take up to 3-4 weeks for production.  Aftermarket rear control arms are HIGHLY suggested due to the additional shock and forces put on the rear end and rear suspension.  It has been shown stock rear control arms do not fair well with a manual transmission.  If track time is in your future, we also suggest reinforcing the control arm mounts to the frame.
