My forward exhaust manifold (cyls 1,2,&3) is badly cracked off where the 2 outboard studs join the intake manifold. The part number according to the manual I have is 180 140 09 11 and the original manifold has 180 142 00 02 WI cast into it, I understand, however, this part would be the same for all 220 W187's of the era (cab A,B,sedan and other)
I'm not concerned if the butterfly intake manifold heating system is functional - only that the casting is intact without cracks and usable.
Please contact me if you have one for sale.
