You will need to give them your pistons and rods separate, the crank, harmonic balancer, flywheel and pressure plate. To my knowlege it cant be done assembled. Each piece has to be done separate. Most shops will have a press to remove the rods from the pistons.
The differences between Las Angeles USA and North Delta Canada are to many to mention but $125.00US is about the same as $225.00 Canadian, I guess there is an industry standard! The sure run good when they've been done though ,What a difference!
