Basement Recessed Lighting

spring3100

Here is my situation.
Placed recessed cans in my basement flush with the bottom of the floor trusses,figuring that the 1/2 inch sheetrock would attach to the trusses also,and I should be good.
However,since it is such a long run of ceiling (42 feet),the drywall contractor has asked that I put up strapping perpendicular to the trusses to prevent a wave effect in the sheetrock due to the truss uneveness.
My question is,will I have to move those cans,and attach them to the strapping,or will they adjust for the 3/4 inch strapping and the 1/2 inch drywall.
These were standard 5 inch cheapo depot new construction lights I put up 2 years back,so all paperwork is gone.

I doubt they would adjust out an inch and a quarter.
Remove the trim and find out how much they will adjust.
