Correct Jack, yes, no, maybe??

[Christopher A.]

I had my 66 427 car judged last week at a regional event and i was informed that my Jack was not original. I'm fairly certain that it is, so i thought i would get the boards opinions.

















Thanks for the opinions and help!

My opinion is worth what you paid for it, but she looks real to me !!

Photos from my 66 that I have had since 1977. The part sticking up would normally be horizontal.

That is NOT a 66 jack !

I did not purchase it, but it came with the car and that is why I assumed it was original.

The judge read the manual to me stating that it should have flat unreinforced lifting arms and that my jack did not and thus, it must be a reproduction.

Looks like it does have flat unreinforced lifting arms ??????

Yes, i know. I tried to point that out, but to no avail.

Tom,

Bummer! I never gave it any thought until now. Must have been changed somewhere between the first and second owner as I purchased the car from the second owner.

Christopher,

Your jack looks like an original to me. The link below has photos of my original unrestored 1966 Corvette jack. I bought my 1966 Corvette in 1979 and I am 99.9% sure that the jack is original. The jack handle (aka lug wrench) has one hole in the handle.

Jerry,

It's not a 1966 jack. There should be a date code. It may be stamped on the large "solid block" near the hex bolt head or it may be on the side of the jack.

According to the NCRS judging manual, 1966 Corvette Jacks were not dated, but i think you may be referring to the specific jack that Jerry posted???

Thanks for the pictures and the help! I was pretty sure it was original since the car had been off the road since 1974, but you never know what might have happened in the past during a flat tire change. Parts getting mixed up in the night from a helper, etc.

Dave,

You got my curiosity up about this jack. The stamp is on the lower scissor at the hex head end and it is 9D. If I understand that, a big if, it would be 1969 and April. Also, on the opposite lower scissor, opposite end, is a paper tag that has writing at the top that is unreadable then two identical rows of numbers that are 3958710 and below that a large GM on the left side with smaller unreadable information to the right of GM but looks to end in lb or lbs and below that again in small letters appears General Motors written out. I have no idea if this is a corvette jack or something else maybe a generic replacement.

If you search the forum, there is a good thread on when jack dating came into production, so depending basic assumption is 66 jacks were not dated.

You have to be sure you have the correct jack handle too - those details are in those threads too.

Jerry,
GM # 3958710 is the part number for a 1969 jack (replacement for earlier models) as shown in my 1969 Corvette Parts Catalog (Oct. 1969) in Gr. 8.820. Since your jack has a tag with the GM part number it probably was sold over the counter. It is dated either April 1969 or April 1979 ("9D"). GM # 3958710 is also listed in my 1982 Corvette Parts Catalog (Nov. 1981) for 53-82 Corvettes (replacement for 53-61, 62, and 63-68 Corvettes).
