I have 1979 Oldsmobile Cutlass with a Chevy 305 in it.
I'm refreshing the motor on a limited budget and have a LH Exhaust manifold with a broken bolt ear near the bottom outlet.

Does anyone know from what vehicles I can find a replacement for this manifold? I assume it could also be found on chevrolets around that same year.

The part number is 471639 OR 471539 (the fourth digit looks like a 6 or 5).

Your help would be greatly appreciated.

 

Sorry, I don't know anything about chevys and never swapped a chevy engine into an Olds. Good luck though.

 

Thank you so much Paul! That's exactly what I was looking for!

This is one of those Oldsmobiles that came with a chevy motor, due to a plant burning down. I didn't swap anything.

 

Oh, ok. I should have remembered that. sorry.
