Just bought an 01 GT from a Mustang Auto shop no less, paid for an engine rebuild got the motor back in the car found out they put JB Weld on the dipstick tube and the dip stick in bent to holy ***. How do I replace the tube? Does the motor need to be pulled out or can it be done while its in the car? I went underneath and it doesn't look like there's any room to replace as is. Want something done right do it yourself.
