Sander,

Sorry, I don't have any measurements nor do I know who has one you can measure.

Question - do you have the cast iron holder on the pan - see first photo?

Attached are two photos; 1 - cast iron dipstick holder on pan, 2 - dipstick tube, which might give you an approximate length

Checked the Parts Books. Part #3718206 1st design 1956 Corvette dipstick tube is 14 1/2 inch OL

Hope this info helps.

Re: 56 Early dipstick Tube picture/dimensions

thanks Gary this will help atleast i now know how it looks like i've read the overall lenght is 14.1/2 but its not clear if thats measured from the top of the cast iron holder to the top of the tube . or from where the cast iron holder is attached to the oil pan ?

and yes i have the correct oilpan and holder on the right, but still in search of an early 56 dipstick......

Re: 56 Early dipstick Tube picture/dimensions

Sander,

That's the OL (total) length of the tube including the part that inserts into the cast fitting on the oil pan.

Finding an early 1956 Corvette dipstick is close to finding the holy grail. Part # 372290 only use is 1956 1st design oil pans.

Gary,

You missed a digit. The 1956 Corvette 1st design dipstick is GM # 3722960 (not 372290) and is described as follows:
"19 13/32 under washer" (March 1957 parts catalog)
and
single piece, A = 17 37/64" B = 18 27/64" (Oct. 1962 parts catalog)

I have two original 1958 Chevrolet 283 dipsticks (GM # 3747979) made by different manufacturers that must be similar to the Early 1956 Corvette dipstick except for the length.
Both measure about 20 5/8" under the washer.
A = 18 35/64" and B = 19 5/16"

One 1958 dipstick is stamped "ADD", "FULL", and with what looks like the top half of an encircled letter along with a rounded off pointed end. It also has one 1 3/4" cutout just below the washer.

The other 1958 dipstick is stamped "ADD" , "FULL", and with what looks like the top half of a small encircled letter "B" (or maybe it's the letter "E") along with a "chisel" type pointed end. This dipstick has two 1 3/4" long cutouts spaced about 5" apart.

The "looped" handle ends measure about 2 3/8" and 2 5/8". I have original 1961 and 1964 Chevrolet dipsticks that have much longer "looped" handles (about 4 1/4" and 4 1/2" or so).
If necessary, I can take a few photos.

Is there two versions of the 3722960 Early 1956 Corvette dipstick?
Does the Early 1956 Corvette have one or two 1 3/4" cutouts?
Does the "looped" handle end measure about 2 1/2" or about 4 1/2"? The dipstick in your photo looks like the longer handle end.

Here are two photos of the 1958 Chevrolet dipstick with the two cutouts that I happen to have in my files.

Re: 56 Early dipstick Tube picture/dimensions

Re: 56 Early dipstick Tube picture/dimensions

My other 1958 Chevrolet 283 dipstick (Eng. stamped "T514C" or May 14, 1958; intake casting date "C2658" or March 26, 1958 ) appears to be the same as the Early 1956 Corvette dipstick EXCEPT for the length. The stamping at the bottom end of the dipstick appears to be the same the 9th photo in Sander's post.
O.L. = 23 1/4" (about 1 1/2" longer than the E56 Corvette dipstick)
A = 18 35/64" (31/32" or 0.97" longer)
B = 19 5/16" ( 57/64" or 0.89" longer).

Gary,

There were two different manufacturers of 1958 Chevrolet dipsticks. I have both types as shown in my previous photos.

Were there two different manufacturers of Early 1956 Corvette dipsticks or just one?

Re: 56 Early dipstick Tube picture/dimensions

Dave,

AFAIK there was a single source for the 56-7 Production installed dipsticks.

Dave------

Even if the early 1956 Corvette dipstick was used for some MD/HD truck applications, which is likely, I would think the PRODUCTION requirement would have been so low it's hard to imagine that 2 suppliers would have been involved in manufacturing them.

Re: 56 Early dipstick Tube picture/dimensions

I have collected many Chevrolet dipsticks (probably about 50 or more) from the 1950's to the 1970's Chevrolets and there were at least 3 suppliers. In the 1958 there were at least 2 suppliers. Didn't the various Chevrolet assembly plants usually buy from the closest supplier?
