in order to shift I have to use two fingers...one to hold the brake and the other to click the shifter....otherwise the whole assembly pushes in....My LBS says the shimano 105's are not serviceable.

so you are saying...if i won the auction at 160....i would be better off paying 99 for the single 105 you posted...than buying the lot at 160 and have 2 ultegra shifters plus the other parts
