Thanks, David (Fla54Chevy3100). What a great series of pics you have on your site. I will bookmark it for project reference later. I see what you mean by the adapter. I helps explain the description left by "cletis". If it means I have to screw around with a drill and tap routine then I may forget the idea until there's more incentive on my part ..it's coming on winter and the garage is full of other plans. David, did you also have your rad re-cored? If so, do you keep it at the same 4 lbs. pressure?
