8.75 out of 74 Truck
Since your speaking of truck 8 3/4, I just picked up a 73 B200 8 3/4 489 housing with 11inch drums, 3.55 with a suregrip and the very short driveshaft. I took it apart this afternoon, everything looks perfect. Now I need to either cut this housing to 66 Dart size and get some axles OR locate an A body housing with axles/backing plates/drums. And then figure out the driveshaft situation. So looks like no Dana for me. Took me 3 months to find this within a 2 hour driving distance. Geez.
