Re: 9 Inch LSD
Unfortunately what they are worth and what people will pay for them are two different things. I have virtually given away some top shelf parts over the years. Everyone whats the stuff, but very few are willing to put their money where there mouth is. After all, car modifying is just a hobby - and a damn expensive one at that.
A rebuilt centre is worth about a grand both here and in the states. Whether or not there is a market for them remains to be seen. I sold a 31 spline nodular centre with new detroit locker, daytona pinion, 1330 yoke, new bearings, and new gears for $1200. It cost over $3000. Nobody seemed to want it............
If you must proceed, get 28 spline. I know they are not as good, but that is where your market will be.
