I saw that you have installed 1.5" coil spacers on some 2wd f150s. On my '01 on top of the coil springs at stock are some rubber caps that I guess keep the top of the spring level in that housing. When putting in the Daystar spacers do you also use those rubber caps. I tried it with them in and it bulges out the side of that housing really bad at the top? Any help word be great. Thanks.
