Caution: You may not get your original parts back! They have a whole song and dance ready for you if you bring in valuable collectible vintage parts. Make sure that you photograph every part and check for GM part numbers. They love to "clean" and paint your new drivshaft to make it more difficult for you to realize that you got all NEW parts back from them. I did not get my original driveshaft back. My guess is that it will be posted on eBay in a few days. Please beware if you if keeping your project original is important to you.
