Hope everyone is doing great,cold here in Missouri and snowy, this might be a dumb question but I am having a hard time getting an answer.I bought some reproduction original chrome valve covers,the breather hole on right side cover has a 1" hole and the driver side has a twist on hole for a twist on oil cap.I have an aftermarket air cleaner and I need to know what breather and oil cap I need to use.My car always had aftermarket valve covers with the 1.25 holes on both covers but i did not like the finish (the chrome finish on the new covers really look awesome) any help would be appreciated. Thanks,Allen
