i was thinking about the RK kit too. but i wanted 4-link and at the time, they didnt have a 4-link long arm upgrade. you could only get that in a kit form. but now they have the triple threat kit out that looks pretty cool.
oh, and it wasnt easy as it may seem. don't get me wrong, i would do it again but it took longer than expected. a lot of trial and error was involved. would've been easier to do a y-link but i didnt want that.
