I made a bracket that bolts to the vertical support in front of the radiator using the bottom two bolts. I also made a “T” bracket that goes to the top of the cooler to that same support. On the bottom bracket I curved the bracket to give it some space to radiator but still clear the vertical tray support. I used reproduction trans lines and extended them under the radiator lower core support. The idea came from crackedback here.
Best pics I’ve got and the upper bracket isn’t on yet. I think it was B+M cooler.
