[DeTomaso] gumball pantera needs to remove a rear ZF stud

[Kirby Schrader]

I would certainly agree with John on the reversing switch.
That thing gets in the way very easily without you noticing.

Back it off all the way and see if your problems go away. If so, then screw the switch back in a little at a time.
You need to remove the cover every time to do this, but it's just time consuming. Not difficult.

Another $1.00 to the fray.
