I also just picked one up, looks similar except mines an 88 and has a yellow fotk. I'm building mine with a silver CK headset, new BB bearings, xt m730 drivetrain, brakes and hubs on RM20 rims. I happened to have a Strong seatpost which I think came on the bike originally, and a 1987 Turbo saddle.
If you need to rebuild the bottom bracket I found a bearing company online that sells the correct bearings with c clips for about $5/each and they work perfectly.
