I was looking at reider racings homepage and noticed that they have third members for 8 7/8 GM truck axels. Is that the 12-bolt used on the blazer? I´ve never seen any bolts to take it apart so I was curious about it. They also have third members for Dana 44D axels but is that the blazer front axel or is it something else? I know there´s a lot of different types Dana 44s. It would be nice if it´s possible to replace the complete third member instead of rebuild the whole axle.
