I just received 3/4" poly spacers today . Instructions do say steel and says on top . Obviously mine are not steel . I also thought they looked familiar so to the garage I went . Come to find out they are exactly the same as 3/4" spacers I already had on the wall left over from 1997-06 Jeep Wrangler TJ. So now I have an extra set of 3/4, 1" ,1.75 and 10mm spacers for my TJs or my Ram . On a TJ they do go on the top but that is a completely different looking spring. Ram no choice but bottom . **** poor instructions on TGC's part .
