Bolt on wheel spacers, yay or nay??

[Root_Drum_Co]

Im thinking about getting some wheel spacers to help get my wheels out closer to flush with my fenders. Ive never had any experience with them so i wanted to see what yall thought. Have any of yall on here tried them? Good experience or no? I have a 69 gmc shortbed stepper with 15x8 blazer rallies. I just want a little more width without having to drop the $$$ for 15x10’s right now.

So spacers...yay or nay?

Thanks guys!!!
