well i hate to say it but its a race car..a 89 FIREBIRD he can just vin swap it...no biggie.and then he can say.something like a guy (that has now past away)built it for me and removed the vin while he was building it.so i bought a 89 firebird and swapped them,and in most states this is legal..we do it here a lot.heck i just put a vin plate on a alston chassis roadster to make it legal.passed with flying color at the oklahoma DMV and highway patrol inspection..my buddy just did it to a 92 mustang also..but it may not be legal everywhere..but you should not have released the car with out it being PAYED IN FULL....
