The Ford engine Lehman marinized was also marinized by Lees, and by Bowman. Maybe others. Base engine parts may be available from marinizers, but Ford tractor dealers are a good source, the engine was used in numerous Ford commercial vehicles incl tractors. No idea if ADC as the Lehman successor can supply marinizing parts to fit a Lees marinization but it`s worth asking, I`d wager Brian has been asked before, he may even know a Lees source.
