hey guys, i bought a radiator shroud for my 68 chevelle on ebay a year or so ago, and it was not the right fit for my car. my car came with a 307 powerglide trans. the serial number on the shroud is 3938164 and its in great shape but it wont work for me. the guy said it was 68-72 chevelle small block shroud. can anyone tell me by the numbers what this fits so i can sell it properly? thanks!
