Yes, that is an earlier version of Rich's article.  Not sure what Rich meant with the foot note.

My data is from CRG's data base.  I can answer questions with the data, but I can't give out the data base.

OK... thanks....

Can you please provide me with a list of possible 12 bolt rear ends that would be factory correct/possible.

My current PC1011 G is too early....

So far I think you listed:

PI  (3.31 12 bolt posi)
PL (3.56 12 bolt..... some sort of 4-speed?Huh?) based on Rich Field's article

any more codes work?

and what would be acceptable axle tube date codes???

I'f just looking for a comprehensive list for my search so I purchase the correct unit.

Thanks so much!

PI and PL are both 3.55 12 bolt axles, PI is the posi unit.
Available ratios for the L48 are:
STD - 3.31 (QL open, OK posi)
Econ - 3.07 (QS open, QW posi)
Perf - 3.55 (PL and PI)
Special - 3.73 (PM open, PJ posi)
           4.10 (QA posi)
           4.55 (QB posi)
           4.88 (QC posi)
Any May to mid June dates will work.  It will take some time to find out all the different acceptable dates for the different axles.  In the end, I am not sure what the big deal is, the axle is not original anyway.  If it were me, I would just leave the PC axle in, unless I found a cheep replacement.

Daniel,

Thanks!!!!    Smiley

I'm thinking about keeping the PC and just adding a traction bar so it doesn't wheel hop as my wife is planning on running the car with my chevelle at Nostalgia drag events on occassion....

If I find a May/early June unit (3.31, or 3.55) at a good price I'll pick it up....

So how accurate is CBTN? Mr Colvin lists 52 different axle codes for 1967 Camaro PA-PZ and QA-QZ.  Or maybe many of these codes are 10-bolt only codes? And 6 months before the build date of the car, while not unheard of, does seem unlikely, doesn't it?

I would not bother adding the radius rod.  While it helps, it does not eliminate the wheel hop.

Yes, a lot of those were 10 bolts and also a good number of Metallic brake 12 bolts.  There are actually a few more axle codes for 67 besides the P and Q axles.  BP is one of the more popular ones (3.08 non-posi 10 bolt).
6 months is not very common, but with the PL axle Rick was asking about, I think it was possible from the data we have in the data base.  With other axle's?  Definitely not.

Daniel,

My friend with the PL axle is also telling me that its a 4-speed "close ratio" axle.

Is that article that I posted of Rich Fields that provides detail on all the axles wrong then?

It also says my current PC axles is a 350/4-speed axle, is that wrong as you said that axles weren't tied to 4-speeds?

If a PL axles is a legitimate match for my L48 4-speed car, then who's correct on the close ratio thing as no M-21's went into L48's correct?

I'm just trying to get a definitive/agreed upon by everyone answer...

Should we disregard Rich Fields article that I posted?

Thanks!

Axles were not tied to the trans.

Rich may chime in, but I think he was just repeating something that he read.

The PC axle was the standard axle for all of the L48 Camaros (stick and auto) at the start of production until the first of the year.

If a PL axles is a legitimate match for my L48 4-speed car, then who's correct on the close ratio thing as no M-21's went into L48's correct?

All I am saying is that it is possible that the PL axle could have been in a L48 4-speed car.  It could have also been in a L48/M35 and a L35/auto and a L78/4-speed car.  It was just one of the optional axles available.

In my old version of my L30/M20 article I attempted to collate and correlate the available axle information of the time.  The footnotes in it come generally from the Chevrolet P&A 30, but we have never been able to verify the background of those note by anything else.  There does appear to be some truth to them, but based on more recent CRG database checks the P&A30 notes don't appear to be 100% accurate.  Which is, in part, why I pulled the axle stuff out of the CRG article.

I call the old article old because it is old.  I note in the CRG article that the CRG article supercedes the old one, and I do this because I want you to read the new one, not the old one.

I pulled the axle info out of the newer version maintained here at CRG because we've done so much new axle work since then that it wasn't worth trying to keep it separately current in this article.  That doesn't help the everyday reader, I'm afraid, as we haven't published all the axle stuff yet, but it may come out this year.

I haven't looked to see if Alan has updated CBTN recently, but his previous axle info was fairly weak (as was the info in my older article), and unless he has found the original axle plant records, I look for the eventual CRG info to be more accurate with regard to axle codes for Camaro.

Rich,

Thanks so much for the clarification!

Another question....  I have heard conflicting information...

Is a PL open or could it have been a posi also?

Also, what are valid dates on a QK (3.31 posi)...  would that be valid in my 06C car?

Thanks.

I believe if the car was from the Van nyes plant it could be a 327, but for a norwood car 4P is a ss350, my car I believe is a 2L 4P and it only was painted one extra time after the factory paint, had the white ss stripe on the header panel after I started to strip it down.

Realdeal,

I have some evidence that some 2L 4P cars from Norwood (specifically as 06C car like mine) was indeed a RS 327 car (L30/M20), so not all Norwood 4P were 350's...

See these pictures.....  They are of a 67 RS 327 car, 4 speed saginaw, square traction bar, dual exhaust coupe.  Not a SS or RS/SS 350 car.

Just wanted to clarify you on the Van Nuys vs. Norwood 4P cars  (both plants made some 4P (non 350) 327 cars...
