600 Tundra Extreme gear ratio change

[turbo mulcher]

2013 Extreme stock gearing 21x49 106 pitch chain I would like to change to 19x49 . the 106 chain looks a little too long , used up most of my adjustment bolt and there is only 1.25 inch between the chains, quite a big loop. Will a 104 pitch chain fit? Bow Cycle couldn't find a chart.
Thanks
