This is all good stuff to know, Roger. Thanks for posting! I picked up an 8.8 rear end to swap into my '66 F100 at half-price day at Pickyourpart a while back. It's from a '93 Gran Marquis with 3.55 gears, limited slip and disc brakes. It will be replacing the old Dana 44 limited slip with 3.54 gears whenever I get around to it. My 8.8 appears to be in good shape from a car that doesn't appear to have been abused but you never know. It's good to have foreknowledge of potential problems to contemplate when you're sitting along side the road waiting for the tow truck! Ha! Great pics!
