Drop Spindles Wont Align

[71stub]

So I just put my drop spindles on from ECE with all new ball joints and tie rod ends, but when i took it to get aligned the guy said he couldnt get the camber just the way he wanted it because the bolts going through the frame and into the upper A-arm were not long enough and he ran out of adjustment before he got the camber where it should be. I know this guy very well and he has been aligning cars for 40 years so hes not filling me full of crap and i looked underneath and there is not many threads left showing through the nuts. Has anybody else had this problem? Can i replace the bolts or do i contact ECE? Thanks in advance.
