I sent them an e-mail before ordering, This is what they said:
"Rick,

Our listings show that the 2000 Ram 2500 with the V10 requires our 3/4 unf-16 oil filter adapter. The product number is GS-AF2."

 

It should be the 3/4 unf-16 adapter.

 

thanks guys it's on it's way..now for the trans temp did you need a adapter for the service port or will it thread right in? this truck is my only transportation i wont have a ride to the auto part store once i start thanks again

 

It will thread right in.

 

very good thanks

 

have a question why have oil temp?when the water temp is the same from what ive been told

 

For one, the stock temp gauge is very slow reacting and not very accurate. I often see a 20 degree swing on the Glow Shift that barely registers on the stocker. It never hurts to monitor your engine more precisely.

 

wouldnt it be easier to just tie in a engine temp instead?

 

how are you guys running your water temp gauge sensors i looked for a t fitting for the stock location but no luck please post pics

 

Glow Shift has an adapter that goes in the upper radiator hose. Probably the easiest way to do it.
