Well in this case, let cooler HEAD prevail, it is only a /6.
The old radiator decided to give up on me. The top tank cracked where its attached to the bracket, it had already been repaired there once, so rather than adding another bandaid I decided to go with a new cross flow aluminum radiator. Its a universal fit 22" from Speedway Motors. It came without any brackets so I had a buddy of mine weld on some 2" angle aluminum after I fit them to the core support. I also had him straighten the lower neck, it came out at an angle that would have made putting the lower hose on impossible.
The new rad. did not come with a trans cooler so I added an external cooler mounted on 1/8"x1" aluminum strap that I fabbed up.
Since there is no listing for hoses for a '66 with a cross flow radiator, I went to my local O'Reilly store and the manager let me in the back room and shuffle through the hoses. I took some measurements before I went so I had a pretty good idea what I might need, I walked out with upper and lower hoses and a couple gallons of anti freeze.
The hoses fit like they where made for it, don't know what application these hoses are for but they worked perfectly, sometimes you just get lucky.
Heres some pics of how it all came together.
