Convertible bumper jack

[Alan Clark]

My car lacks the mechanism or spring needed to hold the jack in the storage slot on the right side of the trunk.  Anyone have a picture of the item I should find?

There should be clips in each end inside the opening as seen in my picture below. If yours are missing I have plenty along with the screws that attach them.

Jason, are the wooden blocks a factory component? Mine also came with the black wood block for the tire block. 

It is mega hot here this week. Perhaps repainting my bumper jack is something easy I can accomplish this week......

I believe all Cadillacs of the 60s and 70s came with those black-painted triangular blocks of pine.  They did in my 67, 69, and 70 cars.  I plan to take the dimensions off those and prepare a block for this 1964 car which is missing the block.

Did they come with one or two wedge blocks ?

[Alan Clark]

One block in each of my cars - except the 64.

[Jason Edge]

63's and 64's had one block.

Thatd be great! I think I have mine kicking around here somewhere. Let me know what the dimensions of yours is. I think mine was split in two it was so dry. Id like to remake mine as well.

Measurements of the block in the trunk of my 69 Cadillac:

Picture a right triangle:

Base = 3 1/2"

Height = 5 3/4"

Hypotenuse = 6 5/8"

The block is 3 1/2" thick, so if looking down on the base, you'd see a 3.5" square.

The block in my 67 Cadillac also is made of pine painted black, but the dimensions are a fraction of an inch different.

This is excellent! Thank you! 

I shall remake mine as well

Thanks for this timely post. I forgot about the black wooden block that used to be in my trunk. Not sure where it is now. I recently finished a fence project & had a 6" scrap of 4X4 left over so I just made another with the dimensions you provided. I wish all my car projects were this easy.

It looks great, but the animated picture is spectacular.  The talent in this group is impressive.

Thanks for the picture.  I will investigate.
