Hi to all 409ers I need some of your help.I want to purchase this borg-warner main case with a casting ( T10-1C ) and it has a built date WH1022.Was this main case used on 409 dual quad passenger cars built in augest of 1962 or was it used only on corvettes,or was the (T10D-1) main case used.I have a 1963 Impala with a 409 dual quad 425hp with a built date of (08C) third week of augest 1962.It's very important because I want the correct part.
