You need to order a certified copy of your complete airmen file from the FAA. It takes a little while to get so do that now. Hopefully, you've filled in at least your total time on various 8710's throughout the years. Those are official documents and presumably verified at each checkride, thus are considered as good as your original logbook. Gather them in a nice folder or binder, labeled, and make sure they correspond with your electronic logbook presentation. Interviewers are interested in verifying the accuracy of your flight time, and looking for evidence of checkride failures. Your 8710 history answers both of those. I had a similar situation and expected it to be a focal point during the interviews - wasn't even brought up and I received a CJO from each of the 3 majors I interviewed with. As long as you're proactive and thorough about addressing it, it's not a big deal.
