Seal kit for old gannon box cylinder

[meadorr]

Hi. Having problems finding a seal kit for case 480ck hydraulic cylinder 13534-1 that connects to bottom of gannon box.

Haven't done all the measurements, but rod diameter is about 1 1/8 inches. Alternate cylinder ID is Garrison 42989. Any one know the detailed specs for this cylinder or the seal kit part number?

Thanks
