Downloaded the manual from Jensales.

Found 3 different cylinder types for the D2. 1H813, and 4H6711 First Type and second Type.

I have 2 different cylinders. 1H813 and 4H6711 First Type. Main difference here is 1H813 has a nut on the external pipe.

I don't know about a seal kit, but I have the individual seals on order from Toromont Cat dealer here in Canada.

The piston seal P/N changed from the manual, and the shim is discontinued.

As far as I can tell the only difference between type 1 & 2 is internal on the piston seals. Different type and 2 instead of 1.

I see there is a fourth cylinder type 9F3239 looks very similar to 4H6711 First Type, but all different P/N except for Piston Seal.

Great! We might need the seal for uncle's D2 project, just finishing first the installation of the wheel package from 4WheelOnline on the Superduty. Gonna check out Toromont later.
