Thermo housing

Anyone got the inner section of thermo housing for early 1.6. (the long neck section that bolts to the head and has small T piece off it for hoses).I have few here on good engines , and I have several 1.8 ones (different) but I need early type from mx5 1.6 up to 1993/4.I have the top section with the fan switch attached .I dont want to strip good engine to remove this piece (means timing belt, cam pulleys etc off etc and this only makes nore work for me and customer when buying engine from me.)
