So after yall helping me decide which parts to go with in my other thread i figured id ask a few more questions to get some better advice on. Since i will be getting my gears put in i decided to change all my fluids. Gonna go with Royal Purple everything. (engine coolant, oil, Manual Trans Fluid, and Gear Oil) My ? is how many quarts will i need of the manny fluid and how many quarts for the rear gear install? and by what i have read i should go with the 75w140 right? Thanks
