are you trying to get someone to custom build you a single long arm? or what,
if i had $800 for long arms, id buy the RK 3 link again, then go on a small hooker spree with the left over $300
honestly, long arm kits dont really often get resold... most people roll them onto their next jeep, or sell it to a buddy, etc....
might want to call dc4wd
i think ive seen 2 long arm kits for sale here locally, and it was lower-crust stuff
