Bow Roller Tracker Pro Team 175 size?

[DP72]

Bow roller was gone after a day of fishing. Not sure what happened but trying to replace. I had to stuff a towel in there for extra padding before I winched her down so measuring exactly was tough. Seems like it was 3.75 between the bracket or somewhere around there. I Ordered a CE Bow roller with the bells 4". Just got it and it seems like it's too tight to fit in between brackets. Does anyone with the tracker pro team 175 know if the roller is 3" or 4"? TY

The middle roller on the new one is exactly 4" and in between the bracket looks like about 3.25 so looks like I ordered the wrong one. 3" would fit in between the brackets. Damn!
