Understanding GM T3 Headlight History

Here is a good video about those original T-3 Headlights. If you are restoring your 63/64 Cadillac, you will get to the point where you want he original headlights, but may wonder about their history. I thought this was a pretty good overview and keep a link and thought I would share.

A T3 headlight expert explains the history and differences associated with the T3 headlights used in GM cars from 1956 into the '70's. This was done at the M...

I posted pictures for you of my stock vacuum lines at the rear of the intake
I do not have vacuum door locks
64-429 Edelbrock 1406 and a spectre air cleaner

Make note of the aluminum fitting at the back of the Edelbrock carb ( Carter same thing )
That would be the part you may need to get back to a stock lay out if thats your direction

I think the vacuum lines you now have may in some way be making up for the rear carb fitting that is missing in some way --but not sure

Enjoy

I totally agree with you Tony, the build quality of our cars is outstanding!! Everything to the nicely metal dash, shiny padded door panels, to the chrome metal trim everywhere, brushed  metal door handles heavy thick doors, heavy duty hood and trunk lids, high quality thick leather seats and diamond pattern design,, when you step into a 63-64 Cad, you feel like you are a the president of some big fancy corporation and or someone very important.

At the same time they are very youthful and exciting styled  cars for being a so called “grandpa car” even back then. Nothing grandpaish about our Cads!!

Yes there used to be a time when quality ment something to companies, and that Cadillac was special and it’s own vehicle. Those headlights are no different. Sometimes older things are just plain better to use and operate especially stuff like certain hand tools, vacuum cleaners and older appliances that would just keep on going and not break down.

I try not to  live in the past, but I love to own things from the past that reminds me of how great our country was at making everything. That’s not the case anymore. It’s all about quantity over quality and durability.

A perfect example of the quality that went into most things made in America in these years
The mentality was to have the part last as long as is possible -- unlike the world we live in today with planned obsolesence being the mind set

That is why the quality of the cars we own is what it is -- outstanding quality in many things was a sign of the times in our years in America

Headlights lasting 40-50 years and still working
Now thats a manufacturing feet to admire

Enjoy

Hello I've been restoring a 63 for way to many years. Down to almost done, but have issue with trans linkage, when column in park shift rod 2 inches short. everything original. been trying to find picture of manual rod hooked up from under car to see position of linkage. was wondering if anybody has access for pictures. I wanted to see if my manual linkage is bent  wrong out of the trans if somebody dropped the trans or something. Doesn't make sense why it doesn't work. Thanks for any input…

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

Hello!

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…
