DEERE 390 FRONT BLADE CYLINDERS?

[dirtworksequip]

Does anyone know of any aftermarket cylinders that would work to replace the cylinders on a Deere 390 front blade. I rebuilt mine 2 years ago and the barrels had rust pitting from water laying in the bottom for 28 years. I honed out the barrels before I rebuilt them, but they were far from good. The rebuild lasted 2 years. I priced new cylinders then and they were $1000. each. Seal kits were $300 each. CRAZY MONEY! Now I need to come up with another plan. If anyone has any suggestions, I'm open. I did find used blade that looks to be in good condition.

Thanks.
Sincerely,
