I'm new to this site and not familiar with the search feature.. Forgive me if this topic has been discussed in the past.

I'm in the middle of replacing the radiator support in my 1966 F-100 2wd.. Nobody is reproducing one specific to a 2wd of that year.. I've been told the support for a '65 can be made to fit.. I have before me a '65 support and there is considerable difference between the two.. Before I hack up this new support and ruin it, can someone experienced at this, tell me what changes need to be made, particularly in the radiator mounting area??
