First off congrats on starting your build, start a thread in the DIY section and post some pics! I have to agree with the RRO sintiment. thats where i got my 5" SPOA and i regret it wholey and completely. they have terrible customer service (i called to tell them they sent me the wrong piece and the guy started yelling at me sayin i had to pay for the right part) and some of my parts were rusted when i got them.
What are you planning on doing with you zuk? Rocks? Mud? i started were you are a while ago, its awesome to learn and you learn fast, hopefully wit your step dad it will be guided so you dont always doit the hard way
like i did. Where are you located? its my experience that most the ppl on here love to help if you need it
heres my build, if you have any questions, ask away, ill try to answer
