Hey you Mazda Guru's!

Well I just bought myself my first RX-7, couldnt pass it up for 400 dollars! Of course its got a few problems that need delt with at this price, but all and all it was a good deal, I was able to throw a battery in it and drive it to work for a couple weeks, hour and a half drive each way. Early on I noticed from my experience with cars, what sounded to be throughout bearing noise coming from the tranny, seemed to go away when I engaged the clutch. Then one day while getting on the freeway, normal driving speed on onramp, I went to shift into 5th, and nothing! Motor just revved up. Luckily I was only a few exits from my house. I also noticed when I got off the freeway and starting using the lower gears, that 1 thru 3rd gear were making a bad bearing noise in each gear, but 4th was absolutely fine. I have the tranny pulled and inspected the fluid and bottom of pan, lots of shavings in fluid, and even a couple chunks of larger pieces of metal. I have found a working tranny in a local junkyard for 175 dollars. I also have found a rebuild kit online for my tranny for 125 dollars but this does not include a synchro kit. The synchro kit is an additional 235 dollars. I guess my main question is, do I need the synchro kit, and what do you think is the better fix, the used tranny or rebuilding mine.

if its the throw out bearing it should only be making noise when you put the clutch in if im not mistaken.
