Wasn't a 75 drum in the front too? The gas Isuzu engines of that era were the epitome of head gasket-blowing nippo trash, but if you could keep a head sealed they were okay... until the rust monster devoured themShit, I would rock either of those as Yard Art / Emergency Transportation.
We grew up with a 75 LUV, that thing was a blast. Gas Isuzu though, Funky dual wheel cylinder brakes.
