Use new shims. I'm looking at the AM site and the Ford gears alone are $175

Where do you see the gears and install kit for $160? Not to disuade you from the purchase, but LMRS sells the Ford gears, master install kit with the better gt500 pinion sleeve and bearings, friction modifier, and royal purple gear lube for about $250 before the Stangnet discount. Put this kit in my car 3 months ago.

That's what I used! And thought that kit is what he was talking about.:shrug: I didn't pay attention to his stated price.
 
With my Bronco I went from 3.55's to 4.10's and used my factory shims. I seriously didn't even bother buying a shim kit. Back lash and pattern were perfect. I've been daily driving it for close to a year now and have no issues. Also with my car rear end. I went from 3.27's to 3.73's and used the shims from the 3.73 rear end and everything was perfect. But every single damn Chevy rear end we've had come through my shop has had to have a shim kit.
 
You could if you wanted. Most people would say that you might as well swap in new ones while you're there but if you wanna do a budget set up then go ahead and re use them because 107k isn't too bad I suppose.
 
im only the third owner so it needs some mods
dude, don't reuse the factory bearings. The car is 20+ years old. Do you really want to pull the rear end apart again because you went the cheapo route? Do it right the first time and be done with it. New bearings, seals, gaskets, for the carrier, axles, pinion, etc.
