Here's my dilemma, I have a 1967 Dart with a 67 radiator, 68 block, and a 1975 904.

I ordered what I thought would fit from Classic Ind., Part # MA3450 fits 64-68 A body /6. What came was a Classic Ind labeled part YTC6401 for 64-66 /6 w/904 trans cooler lines, 2 pc. Affixed to that part's label was a second much smaller one in upper left hand corner reading; Part # MA 3450 which looks to attach to a fluid tap on right rear of transmission for a rear pump model I'm guessing. And, the second line dose not line up with ether of the fluid taps on my 1975 904.

My question is which pre bent set of lines would work: MA3453 for 1969-1975 A body with /6 and 904; or do I need to bend up my own to fit my Frankenstein Dart?

The old lines are a hodge-podge of spliced lines connected by compression unions, and rubber lines clamped on with hose clamps.

The stock lines in my '67 valiant were the same as the lines as the ones in my '73 Duster... there was the need
to change out the fittings for the connection at the transmission since flare nuts were different sizes between
the two generations.

FYI.

As I thought, the differences between various years are all dependent on transmission's physical features, tap location (two pump/one pump renditions) and size of fittings.

Where Classic Ind. lists only up to 1975 A body, and my trans most likely came from a 1976-77 (Dart, Aspen, Valiant, Volare). I'm now thinking MA3453 (1969 to 75) will work, perhaps, like you said, only needing a fitting change. Incidentally, fittings on tube set I have do fit my trans and radiator.
