What are the odds?

I have a 68 Chevy II Nova. What are the odds of it having a posi rear end? Where are the markings on it so i can find out what exactly the rear end is? THanks

not good...

look here for info

This is the code i found in the passengetr side tube

BP 0411G1

I think the BP means its a 2.73 open from a 69.

0411 means April 11th

G means Detroit Gear and Axel.

But what does the last 1 mean?

Also i decided to check my 75 and this is what I found

GB O308 1

GB I have no idea, can't find it anywhere

O Pontiac plant

308 day 308

1 day shift.

Jack it up and spin a wheel by hand, if both wheels rotate the same way it's a posi, if they rotate in different directions, it's a pegleg :( good luck :)

*Most* of the time.
The only true way is to pop the cover and check. Odds are if you have to ask if it's posi or not, the rear end could probably use a good cleaning/inspection/and new gear oil.

FWIW, VERY FEW novas left the factory with posi. The odds are stacked high against it being posi, if it's the factory carrier.

You could go do a burnout... two black marks = posi, one black mark = peg leg :D

Try telling that to the old open carrier that came out of my pickup...half the time it left 2 stripes.

Seriously, just pop the cover.
$10 of oil, some peace of mind, and exact knowledge. ;)

Thanks for all the advice. Just curious, has anyone been able to make sense of the codes I posted?

Spin the one wheel and try and hold the other from turning. If you can,t its posi or has been welded.
