The passenger side door mirror will not stay in position. I'm sure it only needs to be tightened. Can anyone tell me the T# for the Torx bolts that when tightened hold the mirrors firmly on my 1990 F150 extended cab? The driver set that I have doesn't include one large enough. I'd like to know if it's a T20, T40 or whatever before I try to get one that will fit

Thanks
