not sure what size coil spacers to buy...?

ok so i got my z71 tahoe lifted about 4 months ago. i went fabtech (yea i know) but im switching out the shocks for fox in a little bit. my problem is that im running 35's and needed to crank up the torsion bars higher in the front to clear the tires. i need to buy coil spring spacers for the rear to level the truck but am not sure if it requires 1 inch or 1.5 inch spacers as i did not install the kit myself due to time. how am i susposed to figure out which size i need?  

you could measure from the center of your wheel to the bottom of the fender flare front and rear and the differance of the two should be your answer. and cranking the torsion bars is never good idea. or so ive herd. in short, it puts way more strain on suspension and driveline components. hope this helps.

yea i know its not too great to do that but i had to choice it needed to be done to fit my tires im running or else it rubs terrible on the wells and the suspension. so now im just looking for the right sized spacers. thanx i appreciate it  

and coil spacers are the only thing i know of to get the back end leveled to the same height  

wat about trimming fenders? or is that not an option. coil spacer are OK but i hear for serious off road use, they are not so good.i relize that the suspension was recently done but lift coils would be the most proper fix. i think. maybe wheel spacers in the front. but ive herd mixed opinions on those.

trimmed the wells and other parts too haha but that was needed in addition to cranking up the torsion bars.
