I see this thread is almost a year old. I need a rear for my 86 which is a 8.25" with 3.55 gears. I found one that someone picked up for their 72 D series. The say it has the 5.5 lug circle but I need to make sure the spring spacing will be correct before driving 4 hours to see it. Is the spring spacing the same for a 72 d100 and the 86 D150? They use the same u joint at the rear so I should be good there. I can always swap axles if the pattern is wrong as it was the pinion bearing that grenaded in my old rear. To think a bearing failure at 515000 miles, what has happened to quality control??
What did the rear end come out of? It might not have been put in because it had the larger bolt pattern and they didn't want to use it.
You may be right, they got it to put in a 72 and did not use it. That would be the optimal outcome for me.
