I got this upgrade from Mancini Racing about six or seven years ago by accidentally purchasing two kits instead of only one. It's part number: MRE-34562 (now listed as MRE-AM34562) and is a great upgrade from the rolled steel factory tie rod adjusting rod. I'd like to get $40 +shipping from 54121 for it, which is $20 off what I purchased it for (price is still the same per their website). Send me a PM if you're interested and I'll get the shipping quote figured out. Thanks for looking guys!
