Old and new C 90 cylinders

Had 6 new Superior cylinders left over from Cessna 170B project. Looks like the fellow who bought the ac isnt able to come up with futher money to buy the cylinders. At this time I'm thinking of using 4 of the 6 new Superior cylinders on the C 90 that I'm building for my J3. That will leave 2 extra new cylinders to peddle. Pistons, pins, rings, gaskets included.
Also, the old Continental cylinders mic standard everywhere -- they are 15 over and have 15 over pistons with less than 800 hours. Serviceable. These should be good for a few hundred hours before needing work. These cylinders will fit C 85, C90, O 200, C 145, 0 300 engines. The 85 takes different pistons....I think.
Cash or a propeller for the C 90-8 on the J3 is what I'm looking for.
