Ok-So all THREE M715 radiators I have leak. The one from the J truck--besides being for an auto--also leaks. 4 bad ones. Anyway I know we've been over this before but rereading the posts I printed off I want to clarify. The Chevelle radiator a few have used-How much trimming does this require? One post says you can leave the passenger mounting brace-which leads me to believe you have to hack the other off??? Or is it a slight trim job? Its between the Chevelle big block and the Summit racing brand one that will require fabbing up a mount-no big deal. At least maybe I'll get 80 to 100 back on the 4 fubar ones I have. Any thoughts???
