9 inch posi help

Looking to switch my stock 9 inch over to posi and I was looking for input on which way to go, Don't want to spent too much but I want to get the best setup I can, what all will I need it has a 302 with a c4 on 17in wheels, thanks

 

Whatever you do, stay away from the mini spool, they are cheap but not intended for street use.

 

i would recommend a trac loc, an auburn, or a true trac. they all will work very well on the street.

 

I found my stock 9 inch Ford Traction Loc unit in a junkyard residing in a 6 cylinder 69 E-100 van so I'm sure they are still out there

 

Will any 9 In posi fit?
How many splines is it supposed to have?

 

Well considering that a Maverick never came from the factory with a 9 inch yours was swapped at some point. It would either have 28 or 31 spline axles. On stock axles, take a look at the wheel hub end of axle if the center is like a cup it is a 28 spline if it has a countersunk hole in the center and two holes beside it they are 31 spline.
You will need a differential with the matching number of splines.

 

I would go w/ an Auburn unit as already suggested,they work great & hold up over a long period of time.
