I have two magnetos for sale. One is a Slick 4370 and one is a 4372. They were pulled off of an XIO-390 and were replaced with E-Mags. One magneto has the impulse coupling and the other magneto will need the Lycoming gear shaft. The 4370 retails for 1029.00 and the 4372 retails for 1175.00. I'm looking to sell the pair for $2000.00. The Mags are zero time and come with the ignition harnesses impulse coupling spacer and spark plugs.
