1967 D100 383/727 radiator replacement

[burnout67]

Hello picked up a 67 d100 383/727
Trying to find a replacement radiator Only seem to find are small block radiators can’t find a big block radiator which I assume is a 26”ish core all the others I see are 22”ish
The 22”ish won’t work as the bottom port lines up directly with oil filter so needs a wider core I’m thinking
Does anyone know what these trucks came with originally for the big block

it does have what looks like a original brake controller on the steering column
Has leafs and coil springs on the rear had 3 gas tanks 1 in back of bed and other under bed behind rear axle looked all from that era
Heavy duty rear bumper diamond plate with heavy duty hitch no A/C does have defrost.
Looks like has to be wider because the oil filter 0n the 383 gets in the way of the smaller radiator bottom port

You can see where that bottom hose rests
The port on this small block radiator the port is direct in front of the oil filter
