dude, kitting an a3 takes maybe 15 minutes longer than kitting an a35 or a55, seriously. it's not bad at all. you just press one bushing out and press a new one in. i'm sure there's videos on youtube and what not of pressing a bushign out. you can do it with a c clamp and an 11 mm socket.
you should try google images for all these things that you dont know what they mean.
good job on using the wiki, now figure out google images
