8 3/4 axels???

Im guessing thats what he charges to narrow them? I dont know i dont mean to jack threads or anything but this is weird that me and you (tyler) both have 75 scamps are about to do the same things to them. I have a 8.75 a body housing with a 741 suregrip and 391's but need brakes and axels. I am considering going through doctor diff but still debating with all these ideas and opinions flying around on this thread.
