Sorry to be so confusing.... I made a mistage on the mission #. It is mission 7 on the walk thoughs.
7. Marked Men
Reward: n/a
Mission For: Phil Cassady
This mission will not be availible until you have completed "Got Protection?" for Marty. Drive Phil's truck to the lock up. Try to keep the truck in perfect or near perfect condition. After you arrive, you will see that Martinez has sent you into a trap. Move the truck after the cutscene so that you can perform a drive by on some gang members, and Phil will also help. After you have taken care of the first group. Get out and equip your pistol to finish the rest of the gang members. Collect their SMGs before getting back into Phil's truck. Ram one of the Stallions blocking the alleyways, and drive out onto the street. Head back to Phil's place. You will soon see more enemies following you in cars, but Phil will start lobbing Molotov cocktails and keep them under control. After you arrive at the docks, the mission will be over.
This is the mission we are having problems with, trying to locate the "lock up"
Thanks to all that replied.
