SOL has nothing to do with getting something off your report that is CRTP.
Dispute the items in writing to the CRAs and you can use either obsolete or 'past credit reporting time period' CRTP is 7-7.5 years (per FCRA) - and the date can't change for any reason. so check the drop off date on your reports (or will report until...) and that is when it should drop.
SOL here is 3 years across the board for credit (except promissory notes) - so I can be past SOL but still within CRTP for 4 more years.
