Buying Used 3.55 Gears
Hi I am looking at purchasing some 3.55 gears off craigslist. They have about 5,000 miles on them and at least in looking them over they seem to be in very good condition. Is there any issue with purchasing used rear end gears or should I be alright?
Thanks in advance

they're not a bad idea and gauranteed they are fine........problem is, you need them set up the exact same way they were in the car they came out of, meaning gotta get the waer pattern back in the same location....being off even a few thousands in shim can cause it to whine outside the original wear pattern

Problem with gears is just as mjr says above, they are already broke in and matching the wear pattern will prove to be difficult at best. Even using the exact shims will not give you a perfect set up due to the machining tolerances of the rear differential housings. Im not to sure what the ford tolerances were on machining the rear differential case, but Im guessing +/- .003 is more than enough to cause your gears to whine if the pattern is not matched.
Heads are common items to get used with no real problems as long as you can inspect them for warping , and have them rebuilt with new springs, valve guides/seals.
Cams are also often purchased used, as long as there is not visible scoring or bluing of lobes or bosses. I wouldn't go the used cam rout myself but it is done often.
