Ring and Pinion installation question

[Local Boy]

Answered my own question. Just was wondering what carrier style our rear end has "open" or "Trac-lok". After looking in the manual, I see that it's "Trac- Lok" --ALOHA

All MM's had a t-lok. Here's a list of parts: http://www.fordracingparts.com/parts/category.asp?catID=28&catdesc=Differentials
