Installing non ABS Ford 9",,,,
Also do 9"s need an additive as the 10 bolts do??
If you are running a posi I am thinking you need an additive of some kind.
I am running a 31 spline soft locker and use no additive.
Also the 9" will take more fluid, more than 2 bottles, less than 3.
Will pull fuse and hope for the best.
Will ask my rep at Wynn's if they have anything for it.
Got 6 Btls of lube sitting downstairs.
Depending on the lube you use (e.g. Redline needs none usually -- I like their shockproof), I would try 1, and if the posi still chatters, try more till it stops.
You say to use dino oil for break-in?

Break in was simple for me, let it run on the rack for five minutes, let cool for an hour. Drive it for 5 miles, let it cool for an hour. Then your ready to rock & roll. Or you could just tow it to the dragstrip and break it in there.
Of course, you should follow the instrustions of the company that built it.Oh yeah the light, tape works good.
