Aftermarket trans cooling lines, do they fit?

I'm swapping from a slant six to a 273/727 smallblock in my 1970 duster. I need to either fabricate some oil cooler lines or by some aftermarkets ones like the ones in the picture. They are suposed to fit: 69-72 All A Body 727

Anyone tried them? Do they fit? I have cheapo headers that hang low.
