All you need for the LRP is the engine mounts. You can use the flywheel and clutch assembly from the stock engine. Make sure you post some pictures of the build.

sixty congrats on the new truck. The first thing I would check are the diffs. Try rolling the truck back and forth and then turn one wheel in each direction to make sure they turn smoothly. After that check out the spur gear for damage. If everything looks good then reset the needles to factory settings and fire it up. Good luck, keep us posted.
