12 bolt truck rear end puzzle
How do you count splines on axles? The ones in this 12 bolt truck rearend (3896839) (shortened with a spool aka 513 gears) has just 17 splines and 17 gruves. So what posi unit would fit. Most advertize 28,31 or 33 spline.
Can someone explain the spline count to me. Cannot find any type of axle spline like this ,if this is correct. I even wrapped it with paper then rubbed it with a pencil so to get accurate count. I have counted spline on 4 speeds. Cannot figure out what to do. This is on my latest project car. VW beetle 327/turbo400/forty ford nose/Straight axle,disc all round. I just do not care for a spool. Thanks MiMax
