what number kadee coupler for model power hopper

i am thinking of buying some of model power’s 51 foot four bay cylindrical covered grain hoppers. has anyone out there fitted them with kadee couplers? and if so what number of coupler do they take and how easy it to place a kadee coupler and coupler pocket on model power’s 51 foot covered hopper?

Greetings,

If you go to www.kadee.com there is a conversion page for all models.

According to the chart it would be the #5 or #28.

Hope this helps,
