The smog delete tech article I have found states you need the smog delete pulley. Would it not be cheaper to just buy a shorter belt? I did this on my 90 Fox 5.0. I removed the AC and smog stuff and never used either delete kit. I am just curious why people use them???

I've used a shorter belt after deleting the smog pump, and an even shorter belt after deleting the AC, with no issues at all.
