I can think of two ways to get a feel for your EX FICO score. One is to compare credit reports very carefully, the other is to purchase a product entitled Equifax 3-Bureau Credit Report and Scores. It's not FICO, but my experience is the scores are close enough that I don't asssociate it with the contempt of FAKOs. A 3-1 EQ bonus is that all three CRA scores use the formula, and my EX was confirmed very precisely compared to recent years' FICOs, as was the one of DW.
