I have a 1984 d50 and I picked up front and rear end gears out of an 87 raider at the junk yard. I just put the pinion and carrier back in. And there seems to be quite a bit of sop between the ring and the pinion. I pulled everything back out to make sure I wasn't missing any pieces it that I had installed the wrong pinion or something and it all looks good. Anyone ever don't the front end gear swap from 3.9 to 4.625 and experienced this? Was there any changes between 84 and 87 that i am not aware of? Thanks
