[Alcyone]

luckily i picked up a stock rearview which is firm, so i swapped it out immediately
however, the one that i had was in much better shape than this one i put in

i took the mirror off of the metal mounting bracket, and i peered inside the back.. and there appears to be a small nut/bolt combo in there, which might act as a tensioner, but ive no idea how to get at it

noones disassembled these things? everyone just goes the replacement route? thats a shame =\
