Where can I find the V.I.N. on a 63 convertible?  The usual space at the base of the interior windshield on the driver's side has been decimated by weather.

I can't properly thank you all for your information and references to the 'Help' section.  I now know for sure that the car in question is an Eldorado Biarritz..  And I can see that if I proceed I will be going to that Help section first before asking questions.

Much appreciated.  Thank you Kurt and Jason in particular.

Good day Robert,

You really should check out the Help section.

Regarding the tires, there is a good thread in Help that explains it all.

Tires and rims

Comment by Jason Edge on April 19, 2021 at 10:36pm

As Kurt noted there was only the Eldorado Biarrtiz in 1963. Given the fact the Biarritz convertible was the the only body style in the "Eldorado" body series was one of the factors in moving the Eldorado under the "Fleetwood" body series in 1964, thus becoming the Fleetwood Eldorado in 1964. In interested in more details regarding this move from 63 to 64, check out this Help Topic: Eldorado Biarritz - Fleetwood Eldorado: What’s In a Name?

Comment by Kurt on April 19, 2021 at 2:43pm

My understanding is that all Eldorados for 1963 are Biarritz. The other convertibles for 1963 are Series 62. This should be determined by the 3rd digit of the VIN -"E" indicates Eldorado which will be a Biariritz. In the Literature section above, the 1963 Cadillac Brochure only list an Eldorado Biarritz, no other Eldorado models; direct link - http://6364cadillac.ning.com/photo/albums/1963-cadillac-dealer-broc...

If anyone knows differently, please comment.

As far as tires sizes, please refer to the Help section above.

I shouldn't push my luck but I see there are at  least two tire sizes possible for a 63 Cadillac, 9:00.R15 or 225/R15.  I am looking to put tires on what is being sold to me as a 1963 Cadillac Eldorado Biarritz.  I have not yet been able to confirm that it is, indeed, a Biarritz, but if it is, what would be the tire size?  And is there some way of identifying the Biarritz specifically as opposed to the other Eldorado convertible models, i.e., is there a chrome signature of some kind or a difference in trim? If there is another Tech Tip on this kind of information I would appreciate a lead.

You can find this in the Help section above. Here is a direct link to the topic VIN: Where's the VIN?

1963 & 1965 Distributor

Posted by Martin McKercher on November 9, 2021 at 8:34pm 5 Comments

Hi all
I am looking to have an aftermarket distributor made for these year models.
I have fitted a Holley Sniper to my 63' 390 & want the Sniper to control the timing.

This is in the very early stages so I am looking to see if it is viable.
I understand the purists might see this as sacrilgious but the Sniper has made my car soo much better for me.
I am asking to see if there is any interest?

What is the color of this 63 Eldorado - aquamarine or green?

Posted by SK on October 24, 2021 at 2:33pm 2 Comments


I really like the color combination of this 63 Eldorado (sold long time ago by Volocars).

The ad states aqua exterior and green interior but unfortunately there is no pic on the cowl tag.   

Is the exterior color ’Frost aquamarine’ and interior ’Beryl’?

Or is the exterior green, ’Frost green’ and interior ’Emerald’?



Rochester throttle body gasket

Posted by Phil on September 29, 2021 at 8:18am 5 Comments

Hello,  would anybody be able to tell me if I’m using the correct gasket on my Rochester throttle body? It doesn’t  look right to me.  I’m not sure if the carb actually ran with this gasket because I got it used with no history.  Any help would be appreciated …
