NHTSA Complaint #11019450 — 1990 CHEVROLET G20

I JUST BOUGHT THIS VAN USED AND THE OWNER TOLD ME SHE NEVER TOOK IT IN TO HAVE RECALLS 90V074000 AND 91V040000 DONE. I HAVE THIS VAN AT THE TURNER CHEVROLET, MONTROSE, CO AND THEY SAY THE VIN IS INVALID BUT THE LOCAL TITLE AND CAR FAX SAYS IT IS? I DID A TRANSLITERATION AND THE 9TH DIGIT DIDNT MATCH THE REMAINDER SO THUS IS INVALID. I NEED TO HAVE THE RECALL WORK DONE!
