E1956 dipstick

[Joseph P.]

I have an E1956 and looking for a picture of this dipstick. The GM #372260. Or better still the dipstick. Can anyone help?
Thanks, Joe (48633)

Re: E1956 dipstick

Joe,

According to my notes the 1956 Chevrolet Parts Catalog lists the 1956 Corvette dipstick as GM # 3728130 and is described as "19 9/32 under washer". I sold the 1956 catalog several years ago so I can not double check the part number.

My 1957 Chevrolet Parts Catalog (March 1957) lists the 1956 Corvette dipstick (1st design) as GM # 3722960 and is described as "19 13/32 under washer". My 1963 Chevrolet Parts Catalog (Oct. 1962) describes the 3722960 as "single piece" and A = 17 37/64" and B = 18 27/64".
I assume you know the meaning of the A & B dimensions.

I assume GM # 3728130 was replaced with GM # 3722960. The Parts History section index in my 1963 catalog only goes back to 1960. My 1957 catalog does not have a Parts History section.

The 1956-1957 Corvette dipstick (2nd design) is GM # 3722959 and is described as "21 9/16 under washer" according to my 1957 catalog.
My 1963 catalog describes the 3722959 as "single piece" and A = 19 31/64" and B = 20 7/16".
The 3722959 dipsticks sold over the counter in the 1980's was a two piece dipstick riveted together very similar to the 1958-1963 Corvette & Chev. Truck dipstick (GM # 3739830).

The oldest dipstick that I currently have in my "collection" is an original 1958 Chev. Pass. dipstick (GM # 3747979, single piece, A = 18 35/64 and B = 19 5/16). The length "under washer" measures about 20 5/8".

Hi Dave,
Thanks for your reply. I had both numbers 3728130 and 3722960 and the dimensions, can you tell me is the 3722959 looks like the 1st design dipstick, ie. two piece riveted together and the embossment ( full and add ) are the same and does the letter B or M show just above the felt?
Thanks, Joe

the 56 part book list the 1st design as 3722960, 19 13/32 under washer. the number 3728130 does show up in the back of the 56 parts book being replaced by 3722960 on 10-1-56.

Joe,

I once owned an original one-piece dipstick that I removed from a 1957 Chevrolet, GM # 3722959 as per My 1957 parts catalog.

I also bought a new 3722959 dipstick from my local Chevrolet dealer in the early 1980's and it was a two-piece dipstick with a 3" long handle and a spacing between the "ADD" and "FULL" marks that measured about 1 1/32" as best as I could measure. According to my notes "A" measured about 19 9/16" and "B" measured about 20 19/32". I sold both dipsticks to someone a couple of years ago.

I have never seen a 3728130 dipstick or a 3722960 but according to the parts catalogs they are one-piece dipsticks. I would assume that they were the same as the original L1956-1957 Chevrolet & Corvette (2nd Design) one-piece dipstick, GM # 3722959 except for the length and the "A" and "B" dimensions.

The 1958-1963 Corvette & Truck dipstick (GM # 3739830) is a two-piece dipstick. I have had several of these over the years with the earliest one from a 1959 Chev. Truck (Eng. stamped "F721M" with a "G209" casting date or July 20, 1959).

For what it's worth enclosed are 3 photos of my 1958 Chevrolet 283 dipstick ("A" measures about 18 17/32", book is 18 35/64" and "B" measures about 19 5/16", book is 19 5/16"). Note the encircled letter "E" right after the word "FULL". I have other dipsticks with the letters "E", "B", and "M" which I assume are the manufacturers.

Re: E1956 dipstick

my 56 dipstick, out of its original engine(vet is vin 1566) is a one piece dipstick, stamped Add with arrow pointing to a stamped line, and Full with arrow to another line. all info is stamped, not embossed. the distance from underside of the washer to the tip of the dipstick is 19 3/8". i believe it is original to this first design oil pan. mike

Re: E1956 dipstick

Mike,

Does the "A" dimension measure 17 37/64" and the "B" dimension measure 18 27/64" or something reasonably close like 17 9/16" and 18 7/16"?

Re: E1956 dipstick

Re: E1956 dipstick

Mike,

The link below explains the "A" and "B" dimensions of a dipstick.

Does your E1956 dipstick stamping look like the photo below?
"ADD" over "OIL" (small letters w/arrow)
"FULL (large letters w/arrow)

Re: E1956 dipstick

Thanks Mike,
I have #284 and just found an original oil pan. I have never seen an original dipstick so I cann't say weather it is a one or two piece. The book calls for the distance from the washer to the tip is 19 13/32 (3/8). If I give you my address will you send me pictures of your dipstick?
Thanks, Joe

Re: E1956 dipstick

Thanks Dave,
It sounds like it could be a one piece dipstick. The only people that can say is one who has E1956.
Thanks, Joe
