OK, I have an XJ which is totalled and I got allstate. What are my options? ).
You really don't have
any options. You and the insurance company are controlled by the provisions of the insurance policy. The insurance company knows exactly what the policy states. Do you? Do you know it by heart? If not, then you better start reading until you have a good working knowledge of the policy and its limitations.
how does the buyback work?
The insurance company would likely be willing to sell you back the car if you are willing to pay them more than they think they will get for the vehicle (as it currently stand) at auction.
how do I get rid of the carcass later?
Sell it to dismantler for scrap value. They'll pick it up with their tow truck.
does it cost me money to do so?
Depends on the scrap value.
Any suggestions about how to proceed?
Yup. The insurance company is interested in the vehicle that they insured, the particular vehicle that is identified by the VIN number on the policy. They don't care or more accurately, don't know whether the vehicle has aftermarket parts on it. Before you contact the insurance company, put stock parts back on it. Get stock wheels and tires, control arms, front springs, front bumper and any other parts you want or need to keep. Swap those out for the aftermarket parts that are currently on the vehicle. Remove the rock rails and rack. Put you old rear axle back in.
Then and olny then contact the insurance company. They will tow the vehicle away and you will still have your parts.
Keep in mind that from now on, the insurance company has but one mission... to give as little money as it can possibly get away giving you. You, on the other hand, are arguing two opposing views to them.
You are trying to convince the insurance company that your vehicle is worth far more than it is actually worth. When you lose that battle, and trust me... you will lose, you then have to argue the opposite view, that your parts aren't really worth that much. You won't have much luck winning that arguement either.
