Maybe someone here can give me some info. I have a 70 Mach 1 with a 351w and FMX tranny. I have a nine inch with an open diff w/ 3.00 gears. I would like some better gears like 3.70 and obviously a posi. I have someone that will sell me a 28 spline 4 pinion Trac loc with the small bearings. My questions are:
Does the size of the bearings determine whether it will fit in my rearend or not? Or will both size bearings fit in all nine inch third members?
Assuming my rearend is stock, What size bearings do I have the small or big bearings?
What is the diff between the 4 pinion and 2 pinion trac locs?
Would 200 dollars be a fair price for what this guy has?
Last question. Does any third member thats is a nine inch bolt up to my nine inch rearend regardless of the year?
Thanks
