Blimpy, second thought here. If my memory is correct, the cylinders that I sold you were Wheeler Dealer? Give Jim Green a call and see if the pressure is high enough to be OK with the Cleavelands. They might work, and physically fit without the mismatched fork and clevis issue. Or take an old Cleaveland cylinder apart and measure the bore diameter compared to the Wheeler Dealer bore. It is just possible that they would work, and much less expensive than new Cleavelands. Just a thought. Grant.
