Will this work? I thought they were application specfic. e.g. diffrent gear cuts and rotation. More specfically I need one for an NV4500 out of a 1994 3500HD. I would appreciate any guidance as to what I could use. Thanks.

I would go to a drive line shop and buy a new PTO for your NV4500. | | | | | Joined: Sep 2011 Posts: 1,456 'Bolter | | 'Bolter Joined: Sep 2011 Posts: 1,456 | For it to be that simple would require all transmissions to have the exact same gear in the transmission,
NVG4500 PTO not the same as anything else, also use only the specific fluid.
