I require INFO. and availability on the MALLORY "COMPLETE DISTRIBUTOR" for my FERGUSON TRACTOR "Model TEA20". The 4 cylinder engine in my TEA 20 is the ENGLISH VANGUARD with the Lucas Distributor Model D3A4 V160 40243A. I know MALLORY has a DISTRIBUTOR but I know only several of the last numbers of the MODEL ???339F. This is a NEW MALLORY DISTRIBUTOR but I'm unable to read all of the MODEL number on this photo.
