Jeff, I've got a complete 8" out of a 65 Mustang with 0 miles on the rebuild. Can't remember if its a 3:00 or 3:25. BTW we come down to visit friends in Dayton about 1/month or 6 weeks.

Let me check and see if I can get someone to drill a hole in the side of the center section for a fill plug in the 66 on back,the fill plug was on the back of the housing untill 66 and in 67 it went on the center section. I have a 75 maverick rear end in the 55 and a 78 granada in the 37.
