that is the tricky part
start lookin on ebay, and around junkyards and searching the net
usually you get the linkage with the swap, the pedal and clutch master cyl is a junkyard item, so is the shifter and middle console plastics

its really not that hard to do, specially if u are doing it while doing the engine swap

once the engine is out of the car, removing and replacing any underhood subsystem is magically a 10 minute job.
