Originality / Rear floor pan hole

« on: July 16, 2011, 08:35:02 PM »

There is a 3/4" hole on either side, underneath the rear seat.  The hole lines up with a corresponding half moon notch on the rear spring mounting bracket on the underneath side. 

I was just wondering what the purpose was.  Is it supposed to be plugged with something?

Decoding/Numbers / 124377N169642

« on: July 16, 2011, 03:07:03 AM »

I am looking this over.  Not quite a garage find, but 2nd owner car who bought it in 68 and has POP. I am still trying to figure out decoding those numbers. The car has a white vinyl top but the trim tag shows M-M.  Would the top be accurate as a white vinyl?

Maintenance / Convertible Pump Wiring

« on: June 26, 2011, 04:08:05 PM »

I am troubleshooting my tops failure to move.  It would move fine and then stop about half way.  I would wait a few minutes, then it would operate again.  I am thinking the circuit breaker would reset.  Yesterday after it stopped, I could not really get it going again so I began trying to track down the culprit.  The pump motor operates sporadically.  So starting there I need to check if it operating even while no hooked to the hydraulic lines. 

My question regards the wiring of the pump itself.  There are 3 leads, one of which is ground.  Does 12 volts on one lead spin the pump in one directions while 12 volts on the other lead spin it in the other?  Should I be able to test this on the bench?

Decoding/Numbers / Powerglide stamping ID pic

« on: May 13, 2011, 05:58:48 PM »

The stamping on my Powerglide pan does not quite match the pattern described in the drivetrain page in such that I can not locate a letter code for the month.  The only letters I see are the beginning "T" and the trailing "D".  My internet searching indicates some difference between pre and post 67s.  With a build date of 11B for a 67, I am assuming my Powerglide should follow the pre 67.  That being said, I read the stampings as "T09 01D".  My hopes are that it translates to Toledo, September 1st.  "0901" dayshift.

Of course my hoping does not make it so.

Decoding/Numbers / Head/Block/Intake/Exhaust casting

« on: May 12, 2011, 11:53:44 PM »

Good day,
I am new here and thus far am very impressed with the site.  I have already learned so much.  I have some experience with older Corvettes but am new to the Camaro world.

I recently purchases a 67 rs.  I was informed it was numbers matching though some of that could not be verified at the time of purchase so I am going through all that I can to either confirm or deny.  I like the car anyway, so if it turns out that it is not I will survive.

First off, the block was decked so of course build and application/VIN stamping(s) are gone.  I have recruited an employee of the crime lab and in two weeks we are going to acid etch the block pad to see if we can pull up the stampings.  If so, I will of course document it either way.

I do know the car was originally a V8.  It does have the 4BBL so I am leaning towards the 275 HP, 327. 
Other facts:
Trim Tag Build Date:11B
Head casting:3890462, date K16 (Left side).  Both have the "double humps"
Engine Block casting:3892657, date H66
Intake Casting:3905393, date J46
Exhaust:3892679

As near as I can determine the dates all jive with each other but any input would be appreciated.
