RH Passenger Door Mirror Installation - New Holes Needed in Door

With the RH passenger door mirrors now available, there will be many looking to install one on their 1963 or 1964 Cadillac. A template aligned with the edges of your door, showing the exact location of the 3 holes would be ideal, however, I thought I would share the specs on the holes you will need to install your mirror since my 1964 Coupe de Ville came with the rare dealer installed RH mirror.  

FIRST: I recommend removing your LH mirror. To remove you simply loosen the Allen screw in mirror control handle and remove the retaining screw at front top of the door. Slide mirror back and it will lift up and off the door. You will be left with an excellent template for the RH door mirror. The only difference will be you will not need the larger center mounting hole on the RH mirror. See below for details.

There are many ways to make measurements of the 3 holes on the top, however, this is what I did:
1) I measured from top door ridge up to bottom of mirror hole.  Since the mirror holes are basically parallel to the top door ridge, each measured 3 71/6" from the ridge line.

2) I measured from front door edge back to the forward edge of the hole. Measurements were 2 3/16", 3 11/16", and 5 3/16" starting at front hole.

3) I measured diameter of the hole. They are 3/4" in diameter. Note on the LH door more the center hold is 7/8" in diameter due to the center control rod. Since the RH mirror does not have the control rod, you only need a smaller hole for the mirror arm base attachment, and only need a 3/4" hole.

- Attaching Screw Hole in front top of Door. Look at your LH door front top where attaching bolt goes. The RH door mirror attaching screw goes in same location on the RH door. There is a roundish area where the screw hole needs to be drilled.  Drill a 3/8" hole in the very center of the round attaching area. (Note from the factory, I get measurements of 7/16" but do not believe it needs to be that big... just enough to move the screw around to find the thread in the base of the drill.  

- LH Driver Door Mirror Comparison. For a sanity check, I compared all measurements above to LH core doors I have on and all measurements were consistent with and approximate to the RH mirror hole specs above.    

I hope that helps in the installation of your RH mirror! Below are pictures I took that go along with the description above:

Hey guys hope you’re having a great day. I have a question about the choke heater tube. Mine is loose at the intake and seems to be causing a vacuum leak. Any thoughts on how to seal this up?

Torque converter grab when idling in Drive

Posted by Cliff Johnston on June 14, 2021 at 8:47pm 2 Comments

Hi Everyone, been quite a while since i have been on here.

I have had an issue with the idle on my 64 Coupe Deville ever since i have had it.

With the Idle set high enough that it is smooth, but still a nice idle, the RPM seems only slightly too high for the stall of the Torque Converter. And therefore it tends to sit there and grab and lunge a bit. So until now, i have been putting the car in Neutral at the lights to stop this happening.

I've had the car dyno tuned and…


Can you help? Driveshaft Question....

Posted by Chris on May 30, 2021 at 8:55am 1 Comment


Newbie to the group here - we have already found tons of invaluable information on the board, so thanks! We are restoring a 1963 Series 62 Convertible. We are wondering if anyone knows of a source to buy the propellor yoke flange (that bolts to the pinion flange) for the driveshaft? One of our ears partially broke off. Not sure if we can buy just the yoke flange as an aftermarket part, or if it has to be rebuilt by a welder/fab guy? Maybe a salvage yard for a source? Again, any…
