I mounted an 899 on a ram a couple weeks ago at Cabella's they had two like those the bigger is better. Sorry Idon't remember the model number. but the store was the Allen Store and I believe I paid less than $40.00 I hope this helps
Yes, they have universal hole patterns in the plate that will match up with most units. Get the heavy 2" ball mentioned above. You won't be sorry. The smaller ones just aren't enough for the big units.
