UCLA doesn't pay that well, but they do pay higher if someone is already an AP somewhere else. Not much higher, but 85K-90K is what ABDs get.
If anything, she probably would end up making about the same 90K. It seems like the salaries for junior faculty at UCLA range between 85k and 90k. It is very, very unlikely that she would make more than 100k at UCLA before taxes (excluding any research money or benefits).
