I'm going to convert all bumper light bulbs to LED in my 1965 (1964) Series Seventy-five limousine.  Counting the rear fins, bumper (brake, directional and back-up), license plate and front directional and cornering bulbs, does anyone know how many LED bulbs I will need and any recommendations as to the type to use?  Thank you.  Jim

All the info you need is in the shop manual. 1964 Cadillac shop manual electrical section. There is a chart in the back.   Not sure how the 65 shop manual is set up.

The 1965 Shop Manual indicates to use 1964 Shop Manual for 1965 Series 75 Body specific items. If you have a 1964 Shop Manual it is on page 12-98.

I have the manual.  It doesn't tell you how many are used, only the type of bulb.  I already know that, since I made a copy of that page.  I need to know how many to purchase, so I will have the exact number needed once the bumpers are pulled.  Once the bumper goes back on, the bulbs are extremely difficult to replace. Same for the directional lights in front.

Look at the wiring schematic on page 12-102 and 12-103. Each bulb is shown and you can refer bac to the chart on page 12-98. If I were looking at the instrument cluster for example, I would see that I need 7 or 8 1895 bulbs depending on if I had the power trunk options. I think for most lights you can figure out exactly the # of bulbs you need. Only the dash should require cross referencing the wiring schematic to see the actually number of bulbs. For example if you are looking at license plate bulbs you know there are 2 - one on each side. Same for most of the other front and rear park, turn, brake lights.  Also keep in mind that different body styles have different number of lights (e.g. Series 62 except the 63 Convertible) do not have arm rest courtesy lights. Also options (e.g. Power trunk, Radio Delete, etc.) will mean different bulb counts.

I have the 1964 Shop Manual, however, I decided to just take all the bulbs out, since I was replacing them anyway. I just ordered my LED bulbs from: superbrightleds.com. For my ‘64 Sedan, there were 12 bulbs in total for the outside. Yours may have more/less...

Thank you

1963 series 62 convertible transmission issue

Posted by Matthew VanDeWater on June 22, 2021 at 3:03pm 1 Comment

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


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…
