it won't matter... but pass side is clear and free, drivers side has brake pedal linkage and mc (clutch if you have one)
look at the pic above blue fitting on back of pass fuel rail is pressure in
black thing on drivers side fuel rail is the pressure relief out
the back of the distributor has a big plug that hits the firewall, i tubbed my distributor
you either need to move the motor forward (oil pan hits mustII x-member) or make a box for the plug to go into
