I would have thought all ring and pinions would be heat treated to a certain spec, but they actually went a step further with the COPO's, now that is getting what you paid for. Those cars must be awesome from top to bottom.
Thanks for letting me know, the codes puzzled me for a little while.

The charts i read have two codes for a 4.10 Rear
  BV & BE  My question is what is the differance between the two?
   Thanks and everyone have a safe and happy holiday !

Hi Darrell,
Stock housing, yes. I don't have that many shims. Either 37 or 35.  It is all I can come up with.
Richmond gears says minimum back lash is printed right on the gear and mine reads .010.
Is this gospel or can this be played with?  yes four speed car
appreciate the help.

second two pictures are with .035 on pinion and .010 backlash
when I go to .033, the coast starts to pull away from center towards the top of the tooth
thanks everyone

1969 Camaro 12 bolt, 4.10 Richmond gears
I have been back and forth on pinion shims and can't seem to get both the drive side and the coast side patterns perfect.
Drive side can be good and coast side will be off or the other way around. I need opinions.
First pictures, .037 on pinion and .010 BL

My question is: Is there a reliable person to send an original '69 am/fm radio to for repair?
The tuning knob shaft has a little bend in it and the tuning needle sticks.
I did a search and everything on radios is somewhat old.

  Looks just like the one Heartbeat sells. I have one of theirs. 1.718 diameter, very heavy but non-magnetic, right around 5 ounces. I wish I had a real one. 

Thanks. new one it is.

I need advice.
I was going to just buy a new heater blower motor when I noticed the date on the one I took out.  It was dated the same month as the car.  Now I am torn. 
question one:  Should I keep the blower I have and just put it in the basement and buy a new one or have the old one rebuilt?
question two: Who in the world rebuilds blower motors? Mine is somewhat tight.  It turns but it is tight. 
Happy Thanksgiving everyone.
Ron

Thanks a bunch Ed!

back up lights on my 69 say 5961556 and 7 AMI says 916963 and 4 are they after market or what ?

A friend had one. Mid 70s out of Oshkosh. Had it about two years. Oddly enough his name was Jeff also. Black/ white /black houndstooth. I do remember the car needed a brake job and it was so expensive to get it done I think is the reason he sold it. Also, the car ran like crap all the time. I remember him talking about  the insurance price on it too. I am thinking around 1974. Everyone have a safe and happy holiday,   Ron

Good day everyone. Just looking for advise on a top notch place to send a RS wiper moter & a starter to restore. Mabey even chrome plate parts of them.

No way in a million years I would ever find that kind of information without CRG. BIG Thank you! I ordered catalog's from In line tube and amk. 

Thanks for the link 69z28302!  And what is that mark stamped in to Sauron327 clip ? Looks like an anchor in the picture.
