I have a 57 with a Muncie M-20 and stock rearend housing, axles and non-posi 3.55:1 carrier.
I came across a late 3-serries posi case (thin ring gear flange & left hand thread case bolts). But one of the plates is wrecked, all four tangs were ripped off, it has five plates/discs per side.
I want to put the posi in the 57 3.55 carrier but it needs new clutches or at least the one bad plate, the rest don't show wear.
What are the clutch arrangements? Reading one of the service manuals it shows and talks about putting two internal splined discs together with the two external tanged plates on either side of them for moderate street driving or alternately stacking them plate, disc, plate, disc for maximum non slip traction. It only shows an early four plates/discs per side case.
For a late case, which uses five and one is cupped/beveled, do I start with an internal splined disc or tanged plate next to the gear retainer and where do I place the tanged cupped/beveled plate?
This is for a very street driven weekend pleasure cruising 57.
Also, can I install 58-64 axle bearings on 57 non-posi axles to take up that extra 1/8” that might interfere with the posi cross shafts?
