I deleted the spacer and didn't modify my cruise bracket in any way, cleared the aircleaner just fine.
I never did the TBI mods to my 350 TBI, but I did do my 454 before installing it. Modding a 454 TBI is easier as it has no flared parts above, and is already a 2" bore. They are too much to run on a stock 350 though.
I also shaved my throttle shaft, installed a larger pod spacer, 18PSI spring and 90LB/HR injectors.
