Cooking time estimates for beef short plate

[PSULion]

Hi - question .... my ribs have been on for 4 1/2 hours at at 230 degrees - and are at 186 degrees, just switched grates and added chicken, hoping to finish together - once the ribs hit 203, should I wrap and hold in cooler for longer, or will they get mushy? Thanks!

Just ate ours, they were good but a little heavy on salt. 6hr cook, off at 13:00 then into the cooler with a teapot till 17:00. Nice and tender too.
